I'm having a problem with x360ce

To use my ps2 controller in my pc as a x360 controller , I emulate it with x360ce.

But in Castle Crashers, when I press to play local, the game locates 2 controllers!
In others words, I play with two characters in the same time. They simulate all movements but block and magic(buttons R1 and R2).

I've tried it all: I deleted x360ce and related files, uninstalled Castle Crashers and installed again. I don't know what else I could do to fix this.

Could you guys help me?
