I have been using the Live Movie maker for a while now on the same computer.  I have windows 8.1.  I made two movies the other day with no problems.  Today I started to make one and after putting a few movie clips into the movie maker I get a box that says there was a problem and it could not be fixed.  Im forced to shut down the movie maker.  I tried to uninstall and reinstall but still no luck.  Any ideas?    Im not tech savvy and will need to be walked through any fixes.  Thanks
