Can anyone help me get my game controller workng with Pacific Fighters?

Ok, I use a XBOX 360 controller. I don't have an XBOX, I used this for FSX and it works beautifully. Well with pacific fighters it won't recongnize the two front trigger buttons or the right thumb control. Everything else works. Anyway to make it recognize them? I look around with my right thumb and fly with the left in FSX.

Any help would be appreciated.
