Just bought a used MK3 from a Guitar Center employee off reverb, sent the serial to transfer and photos of receipt etc. to NI and turns out it's NFR, not for resale. Support was very rude and said they wont transfer it and basically need to give it back, I've spent thousands on NI stuff and countless hours with their software and gear (endured all the crashes spent even more on a faster computer). I think I'm done with NI and all their ****** after this experience. Anyone want an S88 Mk2, KK Collectors 14, and Maschine Mk3 (unregisterable), message me. This companies tankig fast and just lost another loyal NI user.
