Can't log into warmane.

Hey, my first time ever trying a private server so I downloaded the MoP client from the website using utorrent for windows. I accidently entered my retail email account information in which auto-updated my client so it kept telling me I need to merge my account. So I then read the 'read me' which indicated I'd have to reinstall if I did enter a email address as it would auto update my client. So I just redownloaded the client (MoP for Windows) and it's still saying the same. My realmlist etc is all set to warmane, anyway of fixing this? Thank you.

Hm, make sure nothing is cached on your machine. Also, have you already created an account on our site? If so, make sure you're logging in with that information -- not your email.

Hey, 100% sure I'm logging in with the information that I made my account with. I also have removed all cache even from my retail wow folders just to be sure.
