My files aren't downloading

I'm trying to download the WOTLK client in the link provided by the Warmane page. It downloads everything in the BitTorrent, except Battlenet.dll. I already tried to insert it manually, but it says I need permission. When I try to enter the game, the login screen appears, but I can't log as it says I was discconected from the server.
What could I do? I already tried many different ways to download it and I simply can't!

Now it simply says that i've been disconnected from the server. I already wrote set patchlist logon.warmane.com in the realmlist.wtf.
