Ultimate Facebook plugin

Hi,

I have the above plugin, but when I enter the short code [wdfb_connect] the login button does not show on the page, can you help?

Also how can I set up a facebook registration page on my website? I am using the bbpress plugin and bbpress members only. I am looking to have people register to my website for free via their facebook account (I will not be displaying the registration page on the website, I will be emailing the registration page link to people) . After they have registered and be come a member of the site, they can login anytime via a facebook login page on the website(which will be shown on the site). Could you please tell me how I can set this up on my site with ultimate facebook.

Thanks
