I am trying to do a final save to my movie. This is the error code that I am receiving while trying to save it. Error 0x80070070 with this message. There are missing or unusable fil in your Movie Maker project that are preventing your movie from being saved. Please check that file preparation is enabled in Options, or remove the files and try again. 

All my files are playing in editing mode so I'm not sure why I'm getting this error message. Can someone please help me?

Thank You
