Hi everyone. 

So, I spent a good 3 hours working on a video, and then I went to bed. (I had saved the video along each step of the way. No problems.) 
I woke up this morning and went to watch it again, and I wanted to make a few minor changes. I was editing a clip (trying to split it) when everything but the clip went white and WLMM froze. I thought I'd save my project and reopen the program. But, when I reopened WLMM and tried to open my project, it said that it can't open the file because it "may not be compatible with Movie Maker or be corrupted." Is there any way I can fix this??? I spent a really long time on this video and it wasn't giving me any problems until now. I just really want to get my video back. 

Thank you so much, 
Rachael
