Corrupted File

I'm having a problem very similar to another person who posted on a corrupted file forum thread here. I open my .wlmp file, and movie maker shows nothing on the right side. On the left, however, I can press play, and the movie starts and plays, only now there is a gap of black space in between each scene. Again, the scenes are not viewable on the right side where normally it shows the clips. Please help!
