WMM keeps crashing while adding new video or opening project

I am getting this Movie Maker crash at work, without fail every time WMM tries to go through the process of loading a new video where it says preparing video with the little green bar that fills up.  I have tried everything I can think of.  Reinstalling drivers, reinstalling the program, restarting, etc.  What's worse is there are 4 computers at work side by side that are identical in hardware and it works on the other three.  Since they are shared stations I'm typically on this one that doesn't work.  Please help!
