Nostalrius Begins - Quality wow vanilla realm (1.12)

I tried both my emails and neither one will allow me to login. It says the information I have entered is incorrect. I havent recieved an email for either one either though. Do they send you one when Registering ? I registered here on this website, do i need to register anywhere else ?

Don't use the Feenix WoW client to connect, as it is modified and will NOT allow you to connect elsewhere.
