I started a project and WLMM was acting up in the first place, it froze and had to shut down unexpectedly, and I've had that problem before, no biggie. So I opened up the program and tried to open my .wlmp file from the list, but UUGH, and error message said, "Sorry, Movie Maker can't open this project file. The file might not be compatible with Movie Maker or be corrupted. Please select a  different project file." Are you kidding me?! It took me HOURS to make this dang tutorial/movie and this comes up?! REALLY?! I CANNOT STAND WLMM ANYMORE! This is Version 2012 btw. What am I supposed to do to check if it is corrupt or something. I uploaded AVCHD video files as well as another video file from a different camera (Sony DSC-W650). Is it possible to turn it into an MP4 when I can't even save the file, let alone open it in its own program?
