Hi, 

I have just spent 30+ hours loading video clips and photos to a movie maker project, saving constantly. In the middle of editing, movie maker suddenly closed. On restarting the project cannot be opened with a message saying it is incompatible or the file is corrupt. Please please please, is there any hope of fixing the file or do I have to start from scratch. I have uploaded the file to OneDrive at:

I absolutely love using Movie Maker but get really frustrated by these glitches. Any way to make them less likely in the future? I have downloaded movie maker as part of 2012 Windows Essentials.  Thanks in advance.
