I have a new set with the Arc Pro base and four cars - all working great. I bought a new car and installed the correct digital chip - the car drives and changes lanes etc but when I try to calibrate as per the instructions the car will not move (even with a nudge) - no matter where I put the power slider on the calibration screen. I have tried tapping "lock calibration" anyway, and the car will race but will not count the laps. I have tried re-calibrating all the other cars that came with the set and they all work fine. Any help would be greatly appreciated!
