keyboard/mouse recognition stopped

Look about halfway down the Controller Configuration window and you'll see a section titled "Wiimotes." Everything above that is for GameCube controllers, which is what you've configured. You should set Wiimote 1 to "Emulated Wii Remote", and then configure that emulated remote to use mouse and keyboard. I think you'll also have to set the emulated remote to have the nunchuck extension and configure that as well.
