Nostalrius Begins - Quality wow vanilla realm (1.12)

I attempted to log in and it would say all the messages like, "Connecting," "Handshaking," "Success." But afterwards just say "Unable to Connect." I attempted many times afterwards over the day and eventually it said my account has been suspended and it no longer available for use. My two characters are Kalkzhim and Janquar.
