Have 2 traktor software serial number curious if i can sell/use them.

I have 2 software serial numbers for traktor pro 2 and traktor scratch pro 2, I got these serial numbers when I purchased an X1 and then again when I purchased a Z2. I have a simple question really, is it possible for me to sell or use the serial numbers from the x1 and z2 when I already put the hardware serial numbers into my native instruments account? Or are these 2 linked in a way? Thanks all.

The Z2 software is tied to the hardware serial, as are software serials from the more recent NI controllers.

darn oh well atleast i got 2 extras if i ever need them. thanks!

I'm willing to give it a shot if you de register scratch pro. Let me know...
