No change here. You must have made a change in your computer. Go to your Systems Restore (or just click the Start--->Run and type 'rstrui' which will start it.. if using XP you may need to add the path to the command so type C:\Windows\System32\Restore\rstrui)

After Systems Restore starts up choose "restore my computer to an earlier point in time" (be patient - it may take 2 or 3 minutes)

Pic one of the bold dates that is a date when it all was OK, then click continue (it's all pretty self explanatory). Then just be patient a little while. It will reset Windows to back when you know it was OK and any changes you have managed to make will get undone. PM me if you have any questions or problems and I'll send you my e-mail address.
