I can't login to Lordaeron

I downloaded the Wrath of the Lich King (Old) today and I can't login to my account at all.
Tried changing the realmlist to: set realmlist logon.warmane.com, still can't login.

if you have downloaded the client from warmane you do not need to change realmlist.
That said maybe your password is too long to be insert on client, try a shorter one
