I think I have a corrupted user account.. Lots of symptoms, but among them: I can't uses any of my Office 13 programs even after running a supposedly "successful" repair. I rebooted in safe mode, and I was able to open files with no trouble. So...I created a new Administrator account, logged in as that Administrator, and again was able to open files with no trouble. That tells me there is nothing wrong with the install of Office. I then created a new user. Moved files to the new user, logged in as the new user, and the same problems occur with Office 13. I can't open anything. For what it's worth, both of the users on this desktop have Admin privileges. Before creating the new Administrator and new user account, I was the ONLY user on this PC.
Any ideas? I've been at this for hours. I'd be most grateful for some help.
