Arena Pass

Me and my friends just upgraded our accounts for the arena tournie, how do we actually get on the server? The email says it was open 21/04/10 untill 21/06/10 i think it was. Is it currently open, and if so, how do we get on?

Ive logged in and gone on Realm list, there is no Arena tab (theres russia, spanish english etc) and also there is no realm on my english list that says "Arena one" or anything, is there a waiting time? ive recieved an email with a transaction ID etc so im abit confused ://
