So I've never had this problem before... I had a large movie I was working on, many edits that I don't think I'll be able to duplicate. Well, Windows Movie Maker crashed and my project became corrupted. I'm devastated and about ready to cry.  If anyone could help me at all I would be so grateful! I had saved it half an hour before the crash without issue... I don't know how to restore to previous versions, it doesn't give me any options for that. Any help is appreciated, thank you!
