links not working in the social theme

I have installed the social theme. I am using wordpress 3.1 and buddypress 1.2.8

On the home page there or sign up buttons but every time I press them I get a 404 not found page.

The link that it says it goes to is this http://www.gossipsocial.com/register

Any help on this matter would be great.

Thanks for your time.
