BKSQ Duke Piston - TDS GTNXi 750 screen is blank

[ddtav8r]

I am just coming back to MSFS2020 after about 2 months off. After applying all updates to MSFS, AAO, BKSQ Duke, I am unable to get the 750 to display.
When I attempt to power up the avionics, the 650 turns on and displays the initial "licensed to" screen. 
The 750 displays that same screen for about 2 seconds and then goes blank. 
Running GTNXI PC Trainer 3.6.40 with Pro Upgrade (1.1.0.3)

The 750 works just fine (both positions) in the C414W. Powers up, and I can load a flight plan. Only AC I am having a problem with is the DUKE. 

Any Ideas?
