Outlook 2007 Beta 2

I've been running Outlook 2007 beta 2 for sometime now. I've had few problems but nothing that I could resolve. My latest problem however is a major pain, for some reason yesterday afternoon outlook decide that it would have a problem and so needed shiting down and restarting which I did. Since then everytime I open outlook I get the same problem, it builds the front page and then decide's it needs to restart.

Anyone else come across this problem?

Any ideas on how to fix it?
