Video Playback Failure

Using the beta version of Premiere Pro.

When I open a project I have recently saved and AI enhanced audio in, I cannot get any playback in the program monitor from my sequences. The "play" button changes to a "stop" button indicating that it thinks it is playing, but no audio or video is heard. The timeline marker does not move either. 

To get it to work again, I need to open the project in the production version of premiere pro, save it, then open in the beta version. I then need to re-enhance all of my audio clips. That works every time, until I close premiere pro beta. When I re-open the project in beta, the same no playback issue happens again. 

Any tips or tricks? Im guessing just a bug in beta, because the production version works great minus AI audio enhancements.
