"Sorry, Movie Maker can't start. Make sure your computer meets the minimum system requirements before trying to start movie maker again, and then try to update the driver for your video card if Movie Maker still doesn't start."

I don't see what i would have to change, it worked fine before the update thing... I've tried everything, i've tried every compatibility setting, restoring previous version which still doesn't work. I've tried the troubleshooting option when you right click the program. I really need this fixed before the 15th of September because i have a movie festival to enter and if movie maker isn't working for me by then, then im screwed D:
