Assassin's Creed 2 won't recognize my 360 controller?

[futurefields]

For some reason only this game won't recognize my 360 controller, it's a standard wired one. I played this game on the same PC like a year ago and it worked fine. Anybody else had this issue? Mind you the controller works fine with the PC, I used it 5 minutes ago to play Wolfenstein The New Order and even a different Assassin's Creed game, Revelations, it works on that one too. Only AC2 won't recognize it, yet it recognized it before like a year ago when I played it but stopped after a couple chapters.

It's working now.
