Issues with MSFS B1-Bone Installation

Hi

I purchased and downloaded the B1- Bone from the MSFS 2020 market place (within the flightsim). it then downloaded and installed into MSFS 2020.

However I seems to be having a few issues with the aircraft. I selected the aircraft and made a flight plan from World Map page, (Parked on a Ramp at RAF Mildenhall Air Base) to fly to Prestwick at 16:30hrs Local Time.

On entering the cockpit the lighting is not working after turning on the Main Battery and Ext Power.  It is dark and trying to manipulate any of the lighting controls is useless.

Also cannot start the Engines - tried to follow the built in MSFS Checklist does not help - it does not show the clickable regions for each item.

Exited this flight and reset is with the aircraft on the runway (Engines already running) tried to taxi down the runway to see if I could control the steering using both the steering control on my Throttle or the Rudder Control on my Joystick, but neither of them work and the Aircraft cannot be steered.

Any ideas on how to fix ???

Or do I just suck it up as buying a lemon??
