I'm using win XP but I can't remember what files I was deleting it was a whole folder of what I thought was Junk.....Obviously I was wrong!!!!

I'll try a file recovery to see. Don't fancy reinstalling my whole PC as this would be a real pain as I have about 50gb of music on one of my drives and loads of other stuff on the other one. As i said Maya seems to be the only program affected and it states prob with Maya.exe file
