I bought a Reloop Jockey 3 Master Edition but I can't use it because its licence have used. I would like to get a new licence for myself. I can't play with the controller and it is really annoying. Please help me.
Go to this page and fill out the appropriate Wizard and you will be led to the creation of a service ticket. Only they can help you with license transfers.
