I'm having the same issue.
it happened when I was trying to make my Xbox One controller compatible with Dead Rising 2 and DR2:OTR on my Steam library. Both my PS2 emulator and Dolphin no longer could recognise my controller. So I deleted the XboxcontrollerCE files from dead rising, uninstalled and reinstalled the Xbox One and 360 Drivers for Windows. Now my PS2 Emulator works, but Dolphin doesn't. Shame really. I want to play my copy of Crystal Chronicles and Zelda: TP.
