If you overwrote the wp_ tables with the bbPress installation script, I think the best (only?) solution is to restore your WP database from a backup, then install bbPress with a proper table prefix, like bb_.

Maybe the installation script should check for someone setting the table prefix in bbPress to wp_ and question it or warn that bad things can happen. Or possibly it could check for the existence of those wp_ tables already, and warn that they’re going to be modified or overwritten?
