BuddyPress Users not showing up

I'm setting up buddypress with the Studio Theme on an MU network. Things seem to be working, but my existing 35 users are not showing up as users on the buddypress installation. Their blogs are showing up. The users and blogs were created previous to installing buddypress. How can I add the members so they show up in Members Directory, etc.?

site: http://mysnowpro.com - you'll see that both the Members and Activity link are not pulling any data from the User List - 35 members, just myself.
