Thanks for your help. I downloaded the G5 installer, turns out the one I downloaded in December 2021 was v2.0, exactly the same size as the newest download. I went ahead and installed it, and one piece of good news, the error messages are no longer displayed. However, I am still unable to turn it on with the mouse, left clicking or right clicking had no effect. Just a dark screen on the device.
I went into the keyboard commands in xPlane and found where I could assign a keyboard letter that was unused, still could not turn it on.
Any further help you can offer would be appreciated. I'm a novice at this.
thanks again
Paul
