Followed tutorial, can not log in (disconnected BLZ51901023)

So I followed the install instructions and everything is up and running. I am trying to connect using my OS X app after changing the Config.wtf file.

I can not seem to get in at all, "You have been disconnected. (BLZ51901023)

Can i run some default logging or something else to see what is going on? Is there a patched client versos I should be using?
