Hi folks, this is my third attempt to resolve this, so any help would be greatly appreciated. I recently purchased Traktor's X1 Mk3 from my local Dj Store, which came with the free upgrade to Pro4. There is no clue in the box how to get this upgrade. I have reached out to NI via email twice. Crickets. Can someone please advise step by step how to complete this? I feel that my only remaining option is to take this up legally as false advertising. Thanks, Cal
