It's the main error going around, your server is packed full it's labor day weekend and it's HOT in a lot of the States people are playing video games. There's no way around it except to consistently sit there and hope a spot opens in the queue. If you don't have any ties and don't mind rerolling I would suggest going to the JP servers, you'll always be able to play and there is a massive english speaking community there already because of this issue. I just play Warcraft on one monitor while hitting the login every 5 minutes.
