Conquest of the Horde

I've just gotten a new computer, with no WoW client downloaded.. So, I went to download it from piratebay, and I happen to download the European version by mistake and for some reason it doesn't work at all. Even after changing realmlist and patchlist info. Anyone know of a more reliable client download?

I got the client here and the patches here

On the first link, wowwiki, which one is the actual client?

ignore the Wowwiki cause the page is convoluted. on the second one in the menu there is a link for clients.

hope that helps

Much appreciated, friend.
