For a summary of my problem, check out this thread.
Unfortunately for me, I can't run regedit. Or system restore. I can run a few programs, most notable firefox and the MS Office suite. Unfortunately, there is nothing there that can help me.
I can't run .reg files. Nor .exe files. I can't ctrl+alt+delete and start a new program. When I pick a program to open the .lnk files with I get the same message that I started with.
Sorry if this doesn't make sense, I've been trying to fix this for the past 4 hours and I'm very tired. Any input will be appreciated and I will clear up any questions you guys have when I'm more awake.
