Movie Maker Project disappeared? Need help!!!

I was just recently working on my daughter's 3rd year video using Windows Movie Maker. I've been working on this for a couple months now. I save it every 10 minutes or so. I was almost done and clicked Save and I got a popup that I was "Out of Memory" which sometimes happens every so often. Then I tried to save it under a different name and then I got a new popup that said "Unspecified Error". I decided to close out Windows Movie Maker and restart the computer. I then noticed the icon/file for my project was no longer visible. I did numerous searches for it on my computer and also restored my computer to a couple days earlier and the project file did not re-appear. Any help would be greatly appreciate, thanks...
