I had this problem also, here is how you resolve it. Go to joystick setup in the game. Go to where you select the control type (mouse, joystick, etc.) On the right side of the screen is the list of all the buttons on your stick, and an icon that says "SET ALL INPUTS" Hit this button. Because you loaded a new stick, AH has to recognize each button, but only does so when you tell it to do so. It took me a bit, but finally got it. Sorry, I cannot provide screenshots to help, but I am at work right now.
<> Hope this helps.
