Getting server erroro

I keep getting error BLZ51934200 and I can’t connect to the servers. I just want to get into my account to play but every time I hit reconnect, I just can’t get in I don’t understand why.

Hello…I have been trying to log in to Cataclysm beta for over a week now. I get to the character log in page, hit the “Enter World” button, the page changes, as if I was going to get in, then it freezes, a spinning circle appears, and the game crashes. I have reported this several times. No one has replied. I am wondering if this is a problem specific to me? If it will be resolved before Cataclysm debuts? Or (gasp) I will never have the chance to play Cataclysm classic. Please advise, if you can.
