My gun is stopped working on Dirty Harry. When the game is turned on, the gun swivels back and forth for about 2-3 minutes and then stops. I've read other threads with similar problems and most of them state the gun is calibrating itself and to let it go through the motions, which I have but it still won't work. When going into the gun test I can use the (+) and (-) switches to move the gun as intended I believe. Not sure what else to look for at this point. Thanks in advance!
