I started a project in Movie Maker. I came back the next day, opened it up and it played through fine.  When I tried to open it the next time, it just hangs...the movie icon is in the middle of the screen....in the bottom corner it says "1 out of 145" and the timer shows 14 minutes. But that's all that happens. It never loads.  I've tried restarting my computer. I tried uninstalling and reinstalling Movie Maker. Nothing works. My computer is a 64 bit Lenovo, barely used.  Please help! REALLY don't want to start this project over, especially if it might just happen again.
