Hi Alta, 

It sounds like you've run into the bug that has been identified in Flash Player that corrupts PowerPoint presentations with videos and Flash objects. Until Adobe releases an update to fix it, we recommend staying with Flash Player 18.

If a presentation becomes corrupt, PowerPoint will let you know that it found a problem and will ask if you want to repair it. When you repair it, PowerPoint will report that "some controls on this presentation can't be activated" and it'll attempt to remove the corruption. Unfortunately, it usually fails in this scenario, so we created a utility to repair your corrupt presentations.

Here's how to downgrade to Flash Player 18 and repair a corrupt presentation:

You'll also want to confirm when working on your project files that you are working locally as described here.
