World of warcraft patch 3.2.0?

ok, i went to a mirror site and downloaded the 3.2 patch and the final part. now when i enter wow, it tries to download the patch. i thought the problem was taht i didnt apply the patch to the game so i clicked on blizzard updater and it failed to start and said like this: "patch can't be applied because it is missing data for: "enGB", if this problem persists, you may be able to solve it by unistalling and then reinstalling the game." so i dont know what to do and i really dont want to re install WoW. i want to play it today in less then an hour. please help!!!!!
