BP Social - Logged In Links Not Working

I installed BP Social theme along with buddypress but none of the links at the top right hand corner are working. These are the links you see when you are logged in to the site and include: Activity, Profile, Sites, Messages, Friends, Groups, Forums, Settings, Log Out.

This is the error message I’m getting:

Permission Denied
Not Found / No Access
The page you are looking for either does not exist, or you do not have the permissions to access it.

What could I be doing wrong?

Thanks!
