Hi all, this is my first ever discussion, be kind. I recently bought a brand new Maschine MK3 (which I love) and decided to buy a second hand Mac Mini (2018 i7 model) and Maschine Jam off of Ebay to set up a nice little studio. The issue is that the Maschine Jam I bought came from someone unwilling to transfer their license. Secondly, when I decided to register it with NI I was informed that the Maschine Jam was a commercial ex display unit, not for resale. They advised me to return the unit and seek a full refund. I paid about £150 for the Jam and it's in great condition and seems to work fine. Should I get a refund or just accept that I have an ex display product that should never have been sold to me. I mean it's not as if it was stolen or has been damaged in any way. Your thoughts would be much appreciated.
