Nostalrius Begins - Quality wow vanilla realm (1.12)

- Hello, downloaded the client and looked forward to play.. but doesn't work to register, dunno Why

- And what is this verification ? Think that's the thing fucks me up

You won't get much help by just saying that "it doesn't work". I suppose that you've registered an acount at https://en.nostalrius.org/register, logged onto your e-mail and clicked the verification-link in the mail.

Where's the error?
Are you able to logg into your account through the website?
Have you changed your realmlist?

We need more info man
