Welcome to our FAQ page. Here you can find answers to the most common questions regarding our products.


Can I use one license on more than one computer?

Yes, you can use your license on more than one computer. Our license policy allows you to do this as long as both computers are yours.


  • You are the sole user of the software and you have purchased a license.
  • It is possible to install the software on more than one PC as long as both computers are yours.
  • If you want to share a database with more than one person, you will need to purchase additional licenses. Multiple licenses can be ordered in our shop. Simply add a license to your basket and then specify how many licenses you require.

Can I use the program on a computer without an internet connection?

Yes, you can use the program on an "off-line" computer.

Without an internet connection, you will be unable to use the 'Add Stamps Automatically' feature to download information from Colnect's server, so you have to enter all the details manually.

Is there a limit to the number of entries in the database?

There is no limit to the number of items you can enter.

Of course the higher number of items (more than 20.000) may slightly decrease performance when sorting, searching, etc. But this of course depends on your computer configuration.

When you know for sure that your card is valid and that you have entered all information correctly, but your order still gets rejected, you may want to contact your credit card company and ask them for the reason.

My license key can't be validated, now what?

If you want to activate the software with a license but fail to do so, there can be a few reasons why.

  • Firstly, please make sure that you have entered the license key exactly as it was given in your license message. Make sure you enter the key correctly by, including all 20 characters.
  • At the risk of stating the obvious, please check that you are entering the license name in the box labeled "Registration Name" and the key in the box labeled "Registration Key" and not the other way around.
  • Do you have a correct license key for the program that you are trying to unlock? Each CataMates.com program needs a different key, e.g. a Stamp Mate license key will only work for Stamp Mate, NOT on the other CataMates.com programs.
  • Do you own a license for the exact version of the software? A version 2013 license for Stamp Mate will not work on version 2014.

How do I uninstall the software?

The software can be uninstalled from the control panel. Click the "add / remove software" icon, and search for software name (for example Stamp Mate).

How do I transfer the data and software to another computer?

First the good news: You will not have to re purchase the software.

Installing the program on a new computer

  • The best way to get the program running on a new computer is to do a "fresh" install, using the original installer. If you do not have that installer anymore, you can download it from the download page on this site.
  • Run the download installer on the new computer to install the program.

Copying the data to the new computer

  • Now you have to transfer your data. At this point make sure that our software is not currently running on the computer you are about to transfer the data from. You only have to copy the existing databases. Your database file is by default located in the C:Stamp Mate Database folder. In case you have changed the database folder's location, you must search for your database there.
  • Now copy this file to the new computer. We recommend using a USB stick, but you can also transfer the files via your network or by burning the data to a CD.
  • Start the program on the new computer and the welcome window will appear.

Select the 'Open Existing Database' option and search for your database. You can also use the 'Open Database' function in the Manage Database section of the program.

I have upgraded the program but I still see the old version's number. Why?

That sounds like you are still running the old version. This can happen because of several reasons:

  • Maybe the program was still running while you ran the installer of the new version? If so, then the installer has not been able to update the program. Make sure you close the program before running the new installer.
  • Maybe you have downloaded the new installer, but did not run it? Make sure you run the installer after downloading it.
  • It could be you did install the new version in a different folder but are still starting the program using a short cut that points to the old folder? To prevent this from happening, always install a new version in the same folder as the old one, overwriting the previous version of the software. (this will not overwrite or delete any of your data).
  • Finally, try downloading the new version from our Download page again.

If I upgrade to a newer version, will I have to re-enter all my data?

No you won't.

All your existing data will be preserved and immediately available in the new version.

I am having connection problems, please help?

The most common connection problem is with the firewall. Also check the settings for Parental Control Programs.

A firewall is software on your computer which can prevent programs to access the internet. Firewalls are also able to block individual programs, so even if you can visit websites, our programs may still be blocked.

You can follow the steps listed below to solve this:

  • Check that your computer is online. Start your web browser and enter a web address like e.g. www.google.com
  • Check your firewall; it should not be blocking the program from accessing the internet. This can occur especially after installing a new version of your CataMates.com program. In that case, change your firewall configuration to once again allow internet access.
  • Disable your firewall. If that doesn't help, uninstall it. Some firewalls are known to interfere with internet access even when they are disabled.

There are many different Firewall programs. Most of them nowadays come integrated in what is called "internet security" software. Such software contains antivirus software, anti spam programs, and firewall software, all-in-one.

Notes about Firewalls:

  • Firewalls can block each program on your computer separately, not just websites you are trying to access. This means that if you allow access for Stamp Mate, but not for Coin Mate, the first will work and the second won't. Your web-browser is allowed access by default, which is why it works even if a CataMates.com programs do not.
  • Firewalls can not detect program version changes. This means that if a program has changed after updating it to a new version, you may need to tell the firewall to allow it access again - even if you had already done so.
  • What may be the most effective way to get your firewall to ask for new rules for your CataMates.com program is to remove its reference in the program list of your firewall. Once done, start up your CataMates.com program, which should cause the firewall to prompt you to set a new rule.
  • If none of the above mentioned solutions help, you have a problem that we cannot solve. Most likely there is a problem somewhere with your internet software or hardware, which may require support from your ISP.

I can't open the Help file.

If you get an error when trying to open the help file follow the instructions in this Microsoft Knowledge Base article

Each time I start the program I need to input my license key.

If this happens; right-click the program icon and choose "Run as Administrator". Then input the license key and it will be stored correctly.

When I start the program I get "gdiplus.dll not being found (error 126)". Why ?

Prior to Windows XP, GDI+ was not installed with the operating system and need to be installed manually. You can find the download the GDI+ redistributable from Microsoft. If you still get this problem after the installation; manually copy the gdiplus.dll into the Stamp Mate directory.
