My video project has essentially gone blank:

No more audio, no video, and the photo files only appear if I play with the zoom (+) in feature.

Last time it worked, I saved the file and closed Movie Maker (no known error or crash), and I did not move the movie file or the files that I used for the movie file. (They are not in the same folder, however.)

The play function will work, but all that appears are a few photo files, the captions; however, nothing in the storyboard and nothing in the storyboard can be clicked on/cut/isolated/deleted, etc.

I have tried uninstalling Windows Essentials, and tried doing the repair; no luck.

I am using Windows 10.

I have read other comments about Windows Movie Maker not doing well with too many captions/music/transitions; this movie file ia 10:00 minutes with 4/5 music clips and several transitions.
I am happy to remove some of these files to make the Movie Maker happier - I just can't edit the file as it is.

Please help!
