Windows Movie Maker Version 2012 (Build 16.4.3528.0331) 

Both computers have been updated to Windows 10 

I have been working on a memorial video for 3 years using Movie Maker on my laptop and desktop.

All of the files, photos, and mp3's are on a flash drive.

When I try to open the project in Movie Maker I receive an error message:

"Sorry Movie Maker can't open this project file. The file might not be compatible with Movie Maker or be corrupted.  Please select a different project file."

can anyone assist with repairing this file?
