Go to Ge's tutorial page and look under Hblade's tutorials. There should be one about getting a controller to work. Also, if for some reason the controller is unresponsive, restart Ge. That happened to me once
A tree never hits an automobile except in self-defence.
the "unresponsiveness" of the controller happens because if game editor is running, then you plug in the controller, gameEditor wont update any usb plugins. It runs at startup So you have to restart it for it to realize the usb plugin is there.
