Okay im doin a favor for white legion since he has limited acess to the internet.

Okay earlyer white legion got rid of some user accounts on his comp. but when this happened it deleted everything in his valveworldcraft folder, along with a "Mesa 64" map that he had been working on, now normaly we both would say "eh", but this map had 5000 brushes laid down, now its gone, is there anyway to get it back?!

He already tried system resore, and there was no luck there, the valveworldcraft folder is back, but it contains no files and most importantly no mesa 64. Any suggestions? (like try restoring to a latter date?)
