I have made an account under the left menu thing and also downloaded the realmlist and the Cata build. Help :X
Can ye' be a little more specific? What's happening when you try to log in?
Connecting, then authenticating, then the information you have entered is invalid.
For when I type in my log in details of course.
You made sure to change the realmlist to ours, correct?
I had a problem where I actually had to run it in administrator, herp, but I don't know if that's the case.
Also, make sure everything in the realmlist is correct.
Last but not least, make sure you have the exact version, Not the B version, but the A version.
