I downloaded the game and got retail wow

I followed the link to download the game from this site. I ended up with retail wow and I can not log in obviously. I download using BitTorrent. On bit torrent I can see a file called Wow.exe, If I click on that from bit torrent it still takes me to retail. Also in the downloaded file on my computer There is only an application with a blizzard logo that just says WOW. file description is world of warcraft retail when scrolled over. I have tried to down load this twice and got the same results. Any advice?

First of all, download the whole torrent. The client looks exactly the same as the Retail client but if you log in with your username (not email) and password you will be logging in into Warmane.
