Try updating the drivers.
If this does not work go download xpadder at
www.xpadder.com
This should be able to "lay over" the actual in game addon for the controller itself.
Also when and if you do download xpadder you'll be able to pick what button does what as you have to set it up that way.
Xpadder is not hard to set up and I've used it many-a-time with emulators so-on and so-forth.
I hope this helps.
