Hello, my problem is with installing traktor pro on a new macbook. When trying to register the serial number, the message I receive is that it is already been resgistred. May i must uninstall from my old mac ?
No need to uninstall or register again. But of course you can uninstall if you want.
Install latest version of Native Access and klick install on Traktor 3 Pro.
If you have Traktor 2 Pro and use a modern mac os then you are out of luck. Should work on Windows though.
