on a different thread I found a website called bootdisk.com
went to windows xp and I can download files to a disk to fix xp from microsoft
i will do this monday and tell you how it works
I've had a similar prob before, and replaced the explorer.exe, but it would still not run. You can try, but if unsuccessfull you are going to needto backup your stuff you need, and reformat/restore XP like Lord AnthraX suggests.
