Thanks Ryan. I was able to rebuild the desktop. However, now another problem is happening, which has happened periodically before. I can't open my company. I log in, select open company, and am given a greyed-out list of my backups, the only clickable one being a Windows backup. Then I went under open recent company. I select an option, and immediately QB announces it is making a backup, and does. Then the login window opens and has me sign in again. I do, and the process repeats. Now after about the 6th time I have done this, I get the usual green square with option to select a company. I do and the same process repeats. I am exasperated. Any ideas?
