Today after the Windows Updates for the month installed, all of my plugins stopped working properly- not sure whether related or not.
Denoise suddenly opened but suddenly lost the bottom box for Deblur. Tried uninstall and reinstall, didn't fix problem.
Detail and Clarity stopped working as soon as I opened them in both Corel PSP and Adobe PSE 10.
In Adobe PSE 10 I also got an error message that the Entry Point Not Found for Detail and Clarity, though Denoise opened missing the Deblur box.
P.S. Finally, after extensive work on file check and repair in Windows, uninstall plugins and restart, then reninstall plugins, I got them all working again. It seems Topaz plugins (not any others, like NIK) are extremely sensitive to any OS changes. I get tired of the Topaz Plugins not working consistently and having to often uninstall and reinstall. Topaz Plugins just aren't stable on Windows OS- not just one of them, but all of them.
