I put in a request after I put in a request for a new registration code after I bought a 2nd hand Maschine MK3 from musiciansfriend and to begin with they should of never taken one to begin with without the guy unregistering the unit first. I never knew it could be such a pain with this process. I got one email telling me they need proof of purchase along with a photo of serial number which I provided to them so now I have to wait on them to get me a new registration number but know knows when that will be, so does anyone know how long it takes to get a new registration code from a 2nd hand maschine?
