Hi, I recently purchased a Maschine MK3 from a major music supplier second hand. The Device included a serial number card. When I tried to add the device to native access it wont work as it is already registered. The vendor say they can do nothing that the seller obviously didnt release the serial number online and they cant contact them. Is there any way NI can release the serial if I send a copy of the number and the card that came with the device? Appreciate any help on this.
