I purchased an "Amazon Renewed" S88 MK3 from Amazon, When I tried to register it, I discovered that the serial number had already been registered. Do I need to return it. I don't need the free software that comes with the S88 as I already own a Komplete Standard license and various instruments. Do I need to return the S88 to Amazon? One of the keyboard lights is non-functioning which is yet another reason to send it back. I submitted my Amazon sales receipt and a photo of the serial number to Support, but they have not yet gotten back to me.
