This is probably an easy fix: go into your Livestream Settings and activate your livestream.
All better now? :)
If not let us know!
Email, Twitter and Facebook are the best ways to reach us!
Why do we do this?
There's a couple reasons but the most all-around answer is that most of the time users that don't intend on streaming just want an avatar for their profile (which they can change on their Account Settings) and don't need the full profile.
This may change in the future but at the moment a "profile page" won't be activated until the livestream settings are also activated.
