Flysimware has released the Cessna 414AW Chancellor for MSFS!

[dbw]

I just updated to 1.0.2.1

Now interestingly my auto pilot control panel display screen is blank and when I select a function, HDG or NAV, the auto pilot does drive the aircraft but the display stays blank.
I've hunted around for a solution but so far have not come across the answer.

FYI:
SW Version Trainer 20.20.13
GTNXI PC Trainer installed Version 3.6.00

Thanks for any responses.
