Getting black screen when I hit the play button on Bootcamp demo 3.2

I just downloaded the 3.2 trial and now when I load the boot camp demo if I click the play button the scene window goes black and cant do anything unless I alt-tab out or hit ESC. Any idea on what could be causing this?

hmm got it. it was loading the version I was messing with that came with 3.1 I deleted that and loaded the version that comes with 3.2 and everything seems fine
