BuddyPress.org

Hi
I have BuddyPress 1.5.2 installed with WP 3.3, theme is the original Buddypress theme.
When I go up to the buddypress bar at the top to my account>settings>general I get a 404.
In addition, when I go to a group and then to the “admin” tab I either get a 404 or simply no page loads.
Actually looking at it now anything that I click on under My account brings me to a “page not found” or doesnt even load a page.
I deactivated all my plugins, I also deactivated and reactivated BP once, and completely uninstalled it once.
Anyone know what could be wrong?
