Logging in

So... new issue. I have everything downloaded as the guide says, and I can start WoW. I have double backed and checked the config file multiple times, it is named correctly and i have the right server name. It also mentions my log in name for this server which means i pulled something from trying, but it tells me i can't log in with the info i provided. I know for a fact that the username and password i used to log into the freedom portal page is the same. I also use the @freedom.com tag. Any advice?
