Reply to N.I. Is Trying To Make A Happy Customer Have A Sad

So after a year and half of enjoying my S4 we're parting ways. I bought the Scratch upgrade kit when it was first released and slowly stopped using many of it's features with the DVS like the jog wheels, so I decided to simplify and get a mixer. Enter the Denon DNX-1600 . I sold the S4 and tried to unregister the serial#. I have an extra copy of Traktor and was planning on keeping the Scratch upgrade to use with my mixer, buuuuuuut N.I. is claiming that the completely seperate Scratch upgrade kit is locked to the S4 and that they must sell together. My friend has no need for the Scratch upgrade and definately doesn't want to pay extra for it (I paid $120 for it). Explaining my situation to N.I. they claim that I have to give away the Scratch upgrade kit because it's locked to the S4 and then buy the exact same Scratch upgrade kit (another $120) to use with my new Scratch Certified mixer. I'm slightly enraged right now and I'm looking for ways around this stupidity.

Cool Story Bra, I know.
