I have two lcd topguns I'm tring to get working with a new pc I recently installed. When I calibrate player 1's gun it calibrates fine and the pointer light is solid. After I'm finished calibrating the pointer light blinks and I get erratic/sporadic mouse pointer control. When I calibrate player 2's gun it works fine and the pointer stays solid and I have decent mouse pointer control. I don't think it's interference since gun 2 is working fine. I tried using the same usb ports and get the same results. Is this gun hosed? I'm not sure what else to try anybody have suggestions?
