Help! Problem with Bridge

Hi all. Just wondering if anyone else is having problems with Bridge. When I try to open bridge (in PS or bridge itself) I immediately get an error saying "bridge has stopped working" and it closes before it even opens. I have tried everything I could find on the forums (including resetting the preferences in PS and bridge), with no luck. I'm running Vista, 64bit, 4GB RAM, PS CS5.1 trial. Any help would be appreciated!
