Essentials 2012 running Windows 8. Movie Maker/Does not work.

I have Essentials 2012 running Windows 8. Movie Maker does not work at all. I have tried un/re installing and repair. Still no luck. Program opens but as soon as I try to open a file I get an error message: 'A problem has caused the program to stop working. Windows will close program and notify of a solution'. No other issues with the computer and all drivers are updated. I don't use this program often at home so don't know when the problem started (on office computer Movie Maker works fine). But I have been trying for a week now to work on a project and the Movie Maker will not work at all. Help, please.
