It has been persisting for almost a week. I had a professional clear all the viruses and malware from my computer, I did a system restore to before the problem began, and I have plenty of space in my disk drives. It also doesn't seem to matter how large the file I'm working on in. It could be a 300x300 pixel image and it still errs.
By the way, I got a Cintiq 22HD and the problem persists so I know for sure that it's not an issue with Wacom or a driver issue.
