Conquest of the Horde

I've changed my realmslist to
set realmlist coth.game-host.org
set patchlist coth.game-host.org

set realmlistbn ""
set portal us

I know I'm entering my password and username correctly, yet it still tells me I'm using an invalid password or info and linking me to WoW's support pages.

Any help? It's been occuring for 20 minutes or so.

Please do not live up to your name. Read the global announcements, especially the "How to Connect" thread. You need to post an introduction.

Be sure to read the stickies in that forum as well.
