WoTLK problems

Hey Guys.

I have a bit of a problem with WoTLK. i finished downloading the 16gb client and whenever i tried to log in this comes up [http://puu.sh/nPhwK.jpg]. If i continue with the update the game would be literally unplayable cause of errors. I have set my realmlist like so [http://puu.sh/nPhGV.png]. If anyone have and ideas on how to fix this i really appreciate it.

Thanks in advance.

you have to log-in by using your Warmane AccountName, not Email address. In case your client has been updated because of this mistake then you have to download it again

I am dumb. Thanks man. I'll just delete this.
