Nostalrius Begins - Quality wow vanilla realm (1.12)

I leveled a warlock to 43ish and took a break for school, except I've forgotten my login information and now that I've tried so many times to log in unsuccessfully, my account is banned. Anything I can do to fix this?

it's a temporary ban that gets removed after ~15 minutes

you can always use the "retrieve password" feature:
