Where is the "enable joystick" button, can't seem to find it

Are you sure your cpu is seeing the joystick?

Go to set up. Select options, then toggle through your steering controls and select your joystick.

Next use the controls tab and set the buttons up. If you don't do this then the game doesn't know what you are trying to do.

I figured it out, someone uninstalled the joystick from my pc, thanks
