Well I tried again today in the morning and once again it gets stuck in a box saying "Fetching Registration Form" and doesn't do anything.

EDIT: Nevermind it is working. It just took a long time to connect to the server. Now all I have to do is wait for it to register. Woot.

Oh and I tried other jabber servers, but they don't seem to load the transports. Ursine.ca loaded it fast for me.
