--- Comment #6 from Andrew Fenn andrewfenn@gmail.com 2009-01-08 07:25:30 --- You don't need the native xinput.dll what it is doing here in wine's implementation is telling the game that you have no joysticks connected. From your output I can see that xinput hasn't got anything to do with your problem launching the game.
