Conquest of the Horde

My intro was approved, my realmist is set as required, I deletd my WDB file as suggested in the connection guide. Yet, when I try to log in it says the information I entered is incorrect. I am positive that I am using my username and password. I can not think of a solution or why this is occuring. I need help please. It could be that my account was not registered for the game yet but I dont know. My intro was approved as I mentioned before though. Any suggestions?

Did you register your account on the account manager?

Oh no I did not yet, thanks It worked
