Hi! I have there is Cubase Elements of but I want buy Cubase 9Pro on forum KVR. What should the seller do primarily? I have my own USB-eLicenser, is it possible to transfer the license to it, or necessarily need usb dongle seller of?
You are going to need the dongle with the license stored on it. If you live close enough to the seller then you can bring your dongle to them and move the license to yours.
