Controller issue

Hey folks, I'd love some help. I have a PS4 controller and I'm running DS4Win to make it look like a 360 controller. It works fine for other games, and the mouse controls fine, and when I got DEmu in the first place I could configure it no problem, but for some reason it's now just not reading it. I configured the thing no problem in the first place, but now whenever I try it just seems to ignore it.

Please help!

Thank you!
