All content made in the Movie Maker program now presents just a green screen.

I made movie clips with this program. Recently, I went back to review all of the movies I made and now all of the content is green. I can understand if the clips were of a different repack, but I made these with movie maker and only saved the project.  Is there no resolve by way of a download codec or an update?  The only thing that has changed was the upgrade to windows 10.
