black screen while making movie

I recently updated to Windows 10 and I was in the middle of making a movie on Movie Maker.  Where I used to see clear images, I see either black screen or error messages.  The audio is fine and I don't have any problems with the other projects I made.  My driver is up to date.  I recently saved the project from a MEG-4 to a Movie Maker and it corrupted the files even more.  I don't know what to do here.  I would like to avoid downloading anything if possible.
