If your game will calibrate and fire the guns in calibration mode, But will not fire in game mode the issue could be the computer not seeing the Security Dongle inside the computer case. To test this you can see if the gun is emitting the ir laser when in calibration mode but not in game mode. This is very common when changing out the Computer in the game as the security dongle is inside the computer case and will need to be swapped over. If the security dongle’s LED Status light is off it means it is no being read by the computer. Try swapping it over to another usb port either inside the computer case or outside of the computer case.
