Problems with the controller

I just bought a ps3 controller to use it on the pc with the rpcs3 emulator. Following some internet tutorials, I installed scp toolkit and used it to configure the controller. At that point the controller started to vibrate. Then I opened the emulator and clicked configuration> pads> handlers> MMJoystic as instructed. However if I tried to modify the preset controls I could not. So I tried to open the game (God Of War II) but the controller, even though it was connected, didn't work. Could you tell me if I did something wrong or if it's a problem connected to the controller or the game? thanks a lot

You're supposed to use the DualShock 3 handler, no 3rd party tools.
