I re-arranged my desks in the home office earlier today and as a result I moved the PC into another room while I was moving stuff about.
Two hours later everything was back up and running but I now get the above error when trying to open any image in PS CS5.
It's worked perfectly for months and I've made NO software changes to the PC at all. Simply disconnected it from the power for a couple of hours.
Any idea's? Google suggests something about UAC but I turned that off months ago.
