I’m getting a similar problem.
at (Dashboard > ) BuddyPress > Forums (wp-admin/admin.php?page=bb-forums-setup) I click on “Install Site Wide Forums” and the box comes up to install bbpress. I install it. But BuddyPress > Forums shows the same thing (I’m presuming it’s supposed to change).
Through some run arounds through the settings of bbpress, I created a forum and such, but no “Forums” page is created. I manage to find my post at /forums/forum/<em>name</em> but the breadcrumb doesn’t work and both /forum and /forum/forums lead to inexistent pages.
I created /forum page: nothing goes on the page. I placed the [ bbp-forum-index ] code and it shows the dummy topic I created, but clicking it doesn’t work.
I’ve uninstalled and reinstalled to no avail. I’ve tried BuddyPress > Forums > Install Group Forums and noticed no difference.
Maybe it’s just not ready for WP 3.3.
