Bridge CS6 Cache and Freezing Issues

I downloaded Bridge CS6 and I have not been able to use it yet. I am on a MacBook Pro running 10.7.4 and every time I launch Bridge I get the following error:

Bridge encountered a problem and is unable to read the cache. Please try purging the central cache in Cache Preferences to correct the situation.

When I try to purge the cache Bridge freezes up. If I don't try and purge the cache I am unable to navigate to any folders on my computer and it just hangs. I eventually have to force quit to get out of it. So far Bridge CS6 has been completely unusable.

Please help.

Thanks.
