So on Windows Live Movie Maker, I have a problem. Whenever I try and play my files, Windows Live Movie Maker gives me the corrupt thing on them. As soon as I play them, they "corrupt". I need to fix it without harming the project. I have to get this project done in four weeks. I already saved it a few times before the glitch, and even though it said the project couldn't be saved when the files were corrupt, I was still able to successfully save it. But whenever I try to play them, the playback window thing goes black and the thumbnail on the timeline has the corrupt icon. How do I make it not do that, since I checked and the file is definitely not corrupt?
