Hey Mark, I don't remember doing too much before the error started. I opened PS, went to create a new drawing, (from clipboard), and received the error. Tried a bunch of workarounds like opening the file directly, etc. Nothing worked. All of a sudden I couldn't open anything with PS, it just stopped working altogether and giving the same error.
Update: After reading through forums, I tried unchecking hardware acceleration under, Edit/Preferences/Performance...and Ps is back up and running now. Who knows what caused it...? Haven't applied anypdates to graphics drivers recently.
Same problems popped up all of a sudden a few months ago and I ended up uninstalling and reinstalling Ps to resolve the problem. So, this time around it was a little easier. 🙂
