Nostalrius Begins - Quality wow vanilla realm (1.12)

So I just came across this server and am anxious to begin playing. I got the game downloaded and everything works fine. I went to log in and it gives me an "incorrect account information" error every single time. I've created multiple accounts and keep getting the error..just wondering if anyone else has experienced this and might be able to provide some help. Thanks in advance

please make sure you are using the game account and not the forum account.
if you are using the game account, make sure you are using the username / password and not the email address as login name.
