Autothrottle/IAS disengages on 787 with Bravo Quadrant

I’m sorry to bump this thread - Actually I’m not. At all. I have been waiting to fly this aircraft(this is my favorite, the only reason I spent $100 for Premium and $750 for my Bravo Quadrant, which is the cause of the issue) for forever it seems. Nobody has an answer except here: Flight Simulator 787 Auto Throttle - Microsoft Community

Which states my exact issue, but the original poster simply stated “All good now! Problem with the Bravo Quadrant programming.” That’s not very helpful. Despite what drivers I install, despite whether my LED’s work or not, this autothrottle keeps disengaging with the blinking A/T (IAS) light.

Someone PLEASE, please, help me. I have so much going on in my life right now and all I ever really wanted was to fly my 787 that I purchased with an extreme pricetag. I am usually the one who is able to help others with hardware bugs, but I am just too exhausted to keep trying to write registry scripts/batch scripts/etc to try and figure out what the root issue is.

The 787 is buggy when it comes to hardware, for example:
A Saitek/Logitech Yoke after rebooting, if not calibrated + LNAV = Death Dive. Fixed.

I fixed the landing gear bug. I fixed the LNAV bug. I’ve fixed this aircraft to the point where the only issue remaining is that out of nowhere the autothrottle will disengage and begin blinking again. I am unable to replicate this bug. I do not want to replace my $750 quadrant with my cheap plastic saitek throttle just to fly this aircraft. This isn’t fair, someone, anyone who is reading this, you aviation guys are extremely intelligent and I’m begging you for assistance.

Thank you. If you find the bug, no matter how petty it is, message me and I will be very grateful, and my gratitude goes very, very, very far.

My life is going very difficult right now and the only thing that roots me and keeps me clean off Heroin(I quit in 2018) is flying my 747-8, but I really need this 787. Please help me - in a strange ironic way the person who can help me determine the issue may actually save my life. Thank you so much.
