This is a current known issue that our development team will address with future program updates.
In the meantime, you can verify your version by clicking on Menu > About to see which version you are running. The most upgraded software can be downloaded from topazlabs.com/downloads without any additional charge.
In each of the plug-ins, you can click the "Menu..." button and, then, "About...". This will give you the version number of the installed plug-in. You can compare this number to the latest version numbers on our Downloads Page. If you find that you're using an older version, please close the plug-in (and your image editor) and download/install the newer version.
