Alcatar

Hey, I just recently downloaded the client and followed the directions so I could play this game. changed the realmlist.wtf to what it is suppose to be as per instructions. when I launch the game and it asks me to log in with my username and pw, it just says disconnected from server. the account info is correct as I used it to login here, but I was wondering if anyone else had a similar problem and if so, how to fix it?
