Don’t you have a backup? Things are definately possible to resolve here but it would be simpler if you can restore backup and then integrate them. I havn’t tried integrating WP 2.7.1 with bbPRess rc 1 as it makes no sense to me doing that on a live site. WP 2.8 and bbPress 1 will have integration features that will work out of the box.

Consider integrating the stable releases of both WP & bbPress only. I have written a tutorial on this on my blog : http://blog.ashfame.com/2009/05/integrate-bbpress-forum-wordpress-setup/. Let me know if you need more help.
