So, I cleaned my computer again in all the ways I know to do and even used some new recommended cleaners.  Today, when I went back into the project I see no images or videos but a blank work area asking me to browse for images and vids.    Stranger still, the count shows the video to be 18+ minutes in length and the item count in the left corner is still at 182 (see attached screen shot),  When I hit play, it even begins to play, and I see the first two  title screens, and initially I even saw a photo (probably after I tried to re-insert the photos, although they never did show up).  Then it is just blackness.

I did a 'repair' Windows Essentials, too.  Oh, and I did not move any of the images or vids from the original files.  I've done quite a few videos using MM.

Any ideas?  

Thanks in advance for any assistance!
