Project File opens but UI doesn't load

I'm having issues opening a fairly large project file. After the start-up screen disappears, the premiere beta window opens up but nothing is displayed on the screen. I have no idea what could be causing this problem other than possibly the program itself. I've opened it up with the normal Adobe Premiere and it seems to work fine but when I open up the project file on Beta, it doesn't display anything. I've attached a screenshot of what it looks like after it loads up.

I do frequently open this project file on an iMac and on PC when I'm working from home but the last save I opened up were both from the iMac. Not sure if there's something there since I'm kind weary of opening up the same file on two different operating systems. I'd hate to say the file may be corrupted, but since it opens up on the ordinary Premiere, it may not be. Since I don't use many of the Beta's new features, it may be time to switch to the ordinary Premiere program.

Has this happened to anyone? Could it be a bug?

Any advice would be great.
