Hey, my system is Windows 7 64-bit, I tried to to make Photoshop preferences default but I couldn't find the specific files which were mentioned in Adobe page. Anyway, I deselected Type: font preview size in the Photoshop. Then uninstalled all Wacom drivers
. Also updated Photoshop. I tested the program and it didn't stop working.
Then I reinstalled the Wacom drivers from the CD given. After that the Photoshop preferences went back and I had to change them again. I tested the program with Wacom and it seems to work fine. I'm not sure if it will continue working because after I installed Wacom for the first time the program stopped working only after 2 days.
Thank you very much for your advices
