Registration page "Permission Denied Not Found / No Access"

Never mind...I figured it out....

I forget to install BP ... duh!

I'm setting up a BP site using BP Social. I couldn't find a widget for Member activity and thought that maybe I needed another member to make it appear. But when I went to register a test account, I got
"The page you are looking for either does not exist, or you do not have the permissions to access it."

No plug-ins are in use at this time.
