nik once you click connect with facebook is it taking you to a form that you have already filled out? If it is, there should be at the top of that form in small white text a link that says already registered. Click it and you should be good to go. I have had that issue a few times.
That's the problem. I connect with facebook, it thinks for a second, and then the same page pops up asking me to sign in with facebook or register. Maybe there's a cookie or popup setting I need to change.
