Just something to try, as I'm having a different but somewhat similar issue. Try opening Pro Tools and creating a new blank session, let it finish creating the session, then press play and let it run for a few seconds. Also, go into your playback engine and make sure you've got the video engine enabled. Everything cool so far? If so, try opening the session that's giving you trouble and see if it works correctly. If it does, please report back, as I'm having to create a new session every time my interface has been power cycled, or I get either a video or an audio engine error. I've done every bit of troubleshooting both Antelope Audio and Avid can give me, and at this point it appears to be a bug in Pro Tools, but seemingly pretty rare.

Hope that helps!
