Help me,please!! I am so worried!!!

[qyjackal]

I am an IL-2 player,using X52.

Now,I have found a very odd problem:
the Z rotation is normal in the driver test,but it couldn't adjust from 0 to 100 smoothly (if you twist the RH of X52 a little, the rudder to be 100%!!!)in the IL-2 Game!!! Never happened this! I can't endure this for it effects my shooting.

Why could this happen??? It is normal in the driver test!!(OS:XP) But abnormal in the IL-2 Game!!! I think the hardware is OK. It maybe a software problem.

I have tried every method I know but no result eventhough I have reinstalled the Game!!

Could anyone here help me?? I don't want to reinstall my OS!!!!!!
I am very worried about that!!
