Wired Xbox360 controller for Assassin's Creed 2

Hi,

I've used my wired Xbox 360 controller on other games on the Mac (same Mac, same Mountain Lion...) before, but now I download Assassin's Creed Deluxe Edition from Mac Games Store and it just won't work. When I go to the controller settings inside the game, I can't even select this controller. Tattiebogle's driver are installed and when I check them in the preferences pane everything works. As I said: It works on other games as well, just not ACII, and it works with ACII and the same controller on Windows.

Does anyone have any idea how to get past this problem? I would really prefer to use my 360 controller. Keyboard/mouse is no option for me and I would rather not use any other controller. This problem is really driving me mad. All the solutions I found were for connection problems with the wireless controller, but the connection works. It's just the game.

Thanks in advance!

Sabrina
