I’ve the same issue too with bbPress 1.0RC. I tried everything described in http://bavatuesdays.com/integrating-wpmu-buddypress-and-bbpress/ but it doesn’t help.
I found that, after I Log-in into bbPress forum, I can’t log in into WPMU, but if this process is done conversely – it is possible to log in into bbPress.
After firstly logging into WPMU and then into bbPress, there are two the same copies of cookie files.
Any suggestions?

Hi Florian,
there was no problem with “Forum could not be created” in my case.
Manoj Kumar in BuddyPress forum helped me with this problem, here is the solution:
1. Delete all tables created by bbPress from your database
2. Install bbPress without integration with wordpress
3. Login with Key Master
4. Go to admin tab
5. Do wordpress integration
here is the link
