I'm having a problem with Wii Sports Golf. It used to work fine swinging for a few months. All of a sudden, it just won't swing anymore. It stutters / hesitates and is very slow motion. Not sure why. Battery level is full Signal is full Sensor is 3 ft below tv Tv is 32", mounted on wall I stand in the same spot I've always stood playing Golf in the past without a problem. I even tried new batteries. The other games work just fine though. What could be the cause of this? I really need to golf!
