I bought my Machine Studio Yesterday from a pawn shop and after downloading Native Access I Tried to put the serial number in but it says it has already been registered. What can I do?
Usually you need a licence transfer ID if you buy a Native Instruments product second hand. While obtaining this ID the previous owner unregisters the hardware from his account. Usually you should contact the previous owner and ask for this transfer ID. As this is maybe not possible in your case you need to contact NI support.
