Directinput gamepad + Joy2Key

I’m sorry for my poor English, but I hope dev read this.
I was playing siralim2 with using PS2Pad(directinput) + Joy2Key. Today, I noticed this game is supporting directinput recently. All buttons and D-pad is assigned to confirm, menu/cancel and movement. This mean my Joy2Key’s setup is messed up by the function. I want to continue using Joy2Key. Is it possible to disable the function?
