First, download this program here, http://rapidshare.com/files/4538295/...entEx.exe.html
And this program here, www.bitlord.com
I recommend Bit Lord, but you can use any torrent downloader.
First thing you do place the WoWtorrent.exe in your WoW folder. Then you download that ****ty blizzard downloader, open it and then close it. Then run the WoWtorrent program and it should start downloading in the torrent downloader you picked. The final result should be in your WoW folder, in a folder with the patch name
(EX.WoW-1.12.0.5590-to-2.0.1.6114-enUS-patch). Then just run the installer and your Good to go.
