Reply to Native Instruments Maschine License transfer?

So I just bought a Maschine off ebay

the guy initially said he would transfer the license...

now he claims its not possible according to NI...unless I bought it at $599 like he did..

Now I know for sure people have transferred licenses before. This is supposedly the full version and not the academic.

Can anyone shed some light on the license transfer process? It is possible right? How long does it usually take?
