Having Problems in login

Soo i just downloaded the MOP client from warmane..
I created the account in battle.net, etc...
All going well..
But now that im trying to login, with the battle.net account email and password the client just show me a error message saying:
"The information you have entered is not valid. Please check the spelling of the account name and password. If you need help in retrieving a lost or stolen password and account, see [https://www.wow-europe.com/login-support] for more information.

But im sure im putting the correct info in the log in tab..

Any help?

Thank you.

Well ur either putting in details wrong. Or u actually made ur account on retail website. To play here you have to have an account on warmane and use that login.

To log in you have to enter your username not the email,i'm pretty sure its written somewhere on the site but it can be confusing for new people i guess.
