I load into cold and dark state set the aircraft up and OIS is not turning on? The buttons next to it also doesn’t respond then the game just crashes and the plane keeps having a WASM

I'm also having this fault, even after resetting the sim several times. I'm able to work without it and just get my take off perf from SimBrief but it's a bit annoying for it to just be a black screen!

If you are sure it's on at the laptop then try turning the brightness down...yes down just a tiny bit and see if it comes on. This worked for me.

The brightness knob is to the left of the Attitude PFD

I have replied to this question on the forum before. The specific solution is: after updating to version 1.0.3, this interface is disabled by default. Its switch is located in the green box position in the first photo (the second photo is an enlarged detail)

Indeed but if that is already turned on then turning it on again won't make any difference. I and others are having a blank screen with this turned on.
