I just upgraded to CS2 and I am having trouble with my plug-in filters. Any suggestions?
Whenever you are installing third-party plug‑ins, start by following the installation instructions that came with it. You may want to try running the installer to make sure that ALL the components are installed properly.
If you're still having trouble, some plug-ins require a legacy Photoshop serial number.
Choose Edit > Preferences > Plug-ins and Scratch Disks
The Plug-ins and Scratch Disks dialog box appears.
Enter the serial number of the previous version of Photoshop you used your plug in.
If all this fails, check with the manufacturer to make sure the plug-in version is compatible with CS2. You may need to upgrade the plug-in as well.
