Same here with a GameStop pad (x360 compatible)
the config screen recognizes the input perfectly, but then it just doesn't work anywhere (in-game, menues, etc)
further more, the problem seems to be, that whatever axis you use, it always saves the "-" (minus) direction for it, you can just change tabs on the options menu back and forth to see this
so, the problem seems to be on saving the config rather than controlling the game, since it's "correct" that you can't steer neither left nor right since you have (probably and unknowingly) binded both commands to the same input
