BuddyPress.org

I’m using the latest version of Buddypress, downloaded only a few days ago, I’m using my own theme and was playing about with registering the sidebars, I thought perhaps I might have assigned Members to a sidebar I am no longer using but when I reactivate these sidebars which I am no longer using it says there are no widgets registered to them.

Is there a way to reset all the widgets so that none are being used? or any other solution?
