Hello hope all is well, i bought a traktor kontrol s4 m2, had it set up on my pc, registered with an old email, both no longer available. Have visited the NI website and my head is spinning. Ive downloaded native access gone through the support page and nothing makes any sense, tried inputting a serial number in native access, states its registered with some other account (yes my old account) tried both tge software serial number and hardware. The support page states to upload a photo of the serial number and unit, but no where can i upload this.
