It's simple - Windows Movie Maker doesn't work. It opens up, then immediately gives an error message and closes. I really need to use it so can anyone help? Thanks

Go here Movie Maker (http://www.papajohn.org/)
Click on Problem Solving, then Crashes and Hangs. It will tell you what the issue is and what codec(s) is causing the problem, and how to fix it.
