GNS 430/XPlane Install Problem with PFC Avionics Stack

I bought a new GNS 430W from Reality XP, Flight1.  The Avionics stack Garmin Control unit would not connect with either GNS on the instrument panel monitor(old and new). Also, after I downloaded the new GNS 430, the mouse would not work on the outer circle of the FMS knob of the new GNS, nor would the Avionics stack unit connect to it. Now the old GNS has connected to the Avionics stack.  It can be operated normally.  I found where you turn on the PFC stack. It is working great, except for being outdated. I still cannot operate the new GNS with the control on the Avionics stack, or with the mouse. 

 

I am wondering if the GNS Hardware and/or Driver that the previous owner bought in 2017 will not sync with the new GNS because the license is under a different name than mine. If I make the new GNS primary, I cannot control it. Would greatly appreciate your advice.
