Classifieds Plugin - How do I redirect "Register Account" on "My Classifieds"

Classifieds Plugin - On the "My Classifieds" page there are 3 options, Login, Register Account, Forgot? - The "Register Account" tab comes up with a "Not Found" page. I need it to give new users the option to sign up. Even if I can just have it redirect to the buddypress signup page. How can I make this work?
