Audio Hardware Setup! Now it's there, now it's not!

Okay, I’ve just about had it with this thing. I can’t get the Audio Hardware Setup or the Hardware rack now in Cubase Pro 9.0.20. I tried running Cubase as admin. I uninstalled and reinstalled the MR Extension. I even tried the rename extension dll, start Cubase, rename it back and start Cubase again trick. Nothing is working. What is the deal Steinberg? Why is this still flakey since 8.0? None of the other extensions (CC121, SKI for iC Pro, even my Panorama P6) have any trouble.
