11053: An error occurred while attempting to load the movie

The video is an MPEG-1 format and previously played in E-Prime 2.0 Beta.  Inexplicably, none of my .mpg videos will play anymore. 

Normally, I use an [attrib] reference, but even when I switched to a direct reference (and first frame was displayed in E-Prime), I still ran into the error.

I tried uninstalling and reinstalling E-Prime 2.0 Beta...and still nothing.

Any suggestions?
