Can not log in via ultimate Facebook

I installed the latest version of the Ultimate Facebook on a one day old wp mu, buddypress installation and to become member using it worked fine (even though I needed to kill of the Captcha since I myself can not read it.. a refresh button would be highly appreciated :wink: ) but now when trying to log in that really doesn’t work at all.

I end up on the same page I try to log in from and am still locked out of the system.
