09:38:03.4 Starting Plan-Gv4 build 4.0.0.255
09:38:03.4 OS is Microsoft Windows NT 10.0.19042.0

I had to Google where to find it, the Start up log file I obtained from here: " c:\Windows\ntbtlog.txt:  was humungous, copious lines of text, mostly,  "Did not load driver" or some "Loaded driver xyz etc"
I didn't think you needed all that.

It's not a big issue, Plan-G works fine in P3Dv5.3 but sometimes goes into slow mo almost freezes in MSFS 2020

I have been using V4.0.0.255 since Dec 2021 but get reminders of an update to a newer version ?? This seems strange, should I re-install ?

The AP works fine but the numbers are not showing, see pic.

Similar problem here, flying at 14330' at 394kts ? The AP function works but is not showing values.

I'm on V3.2.0.144 with P3D V4.2

Since installing P3D V4.2,  I do not see the ALT/VS/HDG/CRS digital readings, having used PlanG for some years I've become used to using these functions to set course/alt and any inflight changes.

The AP functions all work but setting cruise ALT to say 20,000' means 20x10 clicks from take off.

I have set up the Simconnect .xml and .cfg files for P3D as per your post hoping this might sort things but no change. Hopefully this may be something qute simple.

Best regards, Dave
