I"m trying to do a final project in movie maker, and when I clicked on it, all I got was a blank black screen. I could see the top toolbar, but nothing else. I tried logging in, but it wouldn't let me type in my information. I tried accessing mail and messenger, both of which worked perfectly before, and had the same problem. I've run all the trouble shooting I could find on the support pages: uninstalled and reinstalled the updated versions, restarted the computer, run the programs as an administrator, updated my drivers, made sure my account still worked, etc. Nothing has helped. Now when I click on any of my newly-installed programs, all I get is a black screen - no toolbars, no login screen, nothing.
