Hello, I have this controller: Splitfish Fragchuck. https://world.splitfish.com/media/catalog/product/cache/2/image/800x800/9df78eab33525d08d6e5fb8d27136e95/c/h/chuck_front.jpg The joystick started sticking a little, and then it got worse and worse. Now, it not only sticks very badly, but it moves me in random directions at random times. I have had no luck with a warranty claim from splitfish. Could anyone point me to some resources for fixing or upgrading this joystick? I can't play my favorite game without this hardware. Cheers
