bbPress.org

Hi,

i dident find a new version of BBpress Standalone. So i install WordPress an add BBPress via Plugin.
First my URL look like these:
Forum-Root = http://forum.domain.de/forums/forum/
Forum-Forums = http://forum.domain.de/forums/forum/test1/
Forum-Tropic = http://forum.domain.de/forums/topic/ins-herz-zuerst/
;-(
But after deaktivate (Prefix all forum content with the Forum Root slug (Recommended))
it lock like
Forum-Root = http://forum.domain.de/forum/
Forum-Forums = http://forum.domain.de/forum/test1/
Forum-Tropic = http://forum.domain.de/topic/ins-herz-zuerst/

This look better but i dident want to use WP as CMS oder Blog. I only want a root install.
Look like
Forum-Root = http://forum.domain.de/
Forum-Forums = http://forum.domain.de/test1/
Forum-Tropic = http://forum.domain.de/topic/ins-herz-zuerst/
is there a way to do that?
