SOLVED
I can't figure this out. One of my friends were on my computer a few days ago, when he finished, he shut it down. When I started it up, my proflile was... reset. For example, My active Desktop displays the screen it showed when I first installed Windows 2000 on it. My Mozilla Firefox settings were all reset. Everything I had was reset, except all the other profiles work fine, and everything that was installed is still there. When I go into my documents and settings, and view my desktop there, Everything I had before is shown. It is the same way in safe mode. I even tried repairing it with the windows repair CD. If you have any suggestions, it would be greatly appreciated. Oh yes, and I know I don't have any spyware/malware/viruses because I scanned with Ad-Aware, Spybot S&D, Spyware Doctor, Webroot Anti-Spy, Acronis Privacy Suite, and Zone-Alarm Anti-Spyware, and Anti-virus.something went wrong with windows login, and it created another profile over my old one, but I could still get to my old profile and it's settings via C:\My Documents and Settings, so I just copied all the settings from the old profile to the new one, and it was fixed lol.
