Upgrading Aerofly Professional Deluxe to RC 7

  • What do I need to upgrade from my old Professional Deluxe Mac Version to use RC 7?

    I have an adaptor but no cable and want to connect to my Spektrum Transmitters, DX6 or DX4e.

    Where do I buy what I need?

    Is there credit foe my old version?
