I recently installed PS9 software that came w/Bamboo tablet. Was using PS3 prior. When I tried to do various applications in PS9 (working w/layers, enhancing, random things) I get message, "cannot complete request due to program error." I uninstalled / reinstalled PS9 and it worked for a bit, then again today I get the program error message. What can I do? I dont want to have to keep installing uninstalling.
