Can't log in.

Q u o t e:
I just got back to playing WoW and downloaded it and payed to play but it wont let me log in because it says I may not have a WoW game attached to my account or I might be logging into a different region from the one I created my account in.. Any help please?
Thanks!

WoW accounts now need to be associated with a Battle.net account.

First, you create a Battle.net then associate your game(s).

After all that - you then log in with your Battle.net information. A single Battle.net account can hold up to eight WoW accounts.
