HELP! My 'Documents & Settings' Folder Is Gone... WITH ALL MY STUFF!

[Joe Matt]

Ok guys, after starting up my PC on Windows 2000, I got an error message when logging in where the computer can't find the desktop settings and my profile information, even my documents. It then launches into a temporary windows desktop and asks for me to see an admin (that's me stupid!) Anyway, after some searching I found that in the C: drive my 'Documents and Settings' folder has disappeared, and in it's place is a single generic Windows files with that name. My HD still shows that the files are still on my computers, since there isn't more space on it. What should I do? I'm going to submit this to Kevin and the guys at TSS. For more information, I've installed all the latest Windows Updates and I don't use IE, I have a firewall and antivirus.

All help is appreciated! Many important files are JUST GONE.
