xPilot ATC frequency issue

[1643616 (Tim Waldon)]

That is the ATC Auto-tune feature of X-Plane 12.

Take a quick look at this previous post:

Com1 not tuning/changing to correct frequency in X-Plane 12

When I try to tune Com1 to the frequency listed in the X-Pilot ATC list, the com1 switches right back and changes the standby frequency to the same as the old frequency (before trying to change frequency). I cannot change to ANY X-Pilot frequencies at all. I have tried to uninstall both X-Plane 12 and X-Pilot, without success of fixing this issue.
