Hello, I have bought assassins creed and I download it. I open the game and it opens me the patcher, when finish the ubisoft game launcher turns in a bigger window with a big "play" ****on. I click there and launches me a little windows where says: "Unable to locate or start the game. Please try re-installing the game." I re-install the game and happens the same. (I can in logout mode, but I bought the game to have the multiplayer).
