BuddyPress.org

Recently i installed Buddypress on a new website which runs on WordPressMU. So far, all the pages like Activity, Groups, Blogs are there. However, i can’t seem to access the “My Account” Tab in the Buddypress Admin Bar. Every option i click under the drop down of the “My Account” tab bring me to a “Page not found”. What am i doing wrong? I am new to WordPressMU and Buddypress, please help.
