Issues on login

I first downloaded MoP on Warmane, and I'm really excited to play it again (after WoD my computer just don't run the official game), but, when I try to log in the server, it shows an error. The error says:
"This account need to be converted in a Battle.net account. Please [Click Here] or go to: [https://eu.battle.net/account/creation/landing.xml] to start a conversation."
If anyone can help, I'll be grateful.

(Sorry about my English, I'm brazilian)


Edit: Solved ^^

You should check realmlist first to see if yours is correct.

I just found the error, then I re-downloaded the config.wtf file and run as administrator,that solves the problem.
Thank you anyway.

Glad it worked out for you.
