Once you has upgraded to W10, I guess it should remains activated, although you have made a rollback. When you go for a fresh install, only skip the key number screen by clicking the link (I think it says “I don’t have a serial number” or something like that).
Anyway, perhaps W10 is not going to be the solution…
Today my tabs has become dark green again. I’ve made a reboot, and voilá, there are my gray labeled tabs in working order again

I’ve also noticed a blast in the VST meter when I attempt to open a plugin’s GUI while mixing. In fact, if I do so, it leads audio to stops. I’ve a lot of VSTi runing, and a bunch of plugins too at the same time, but the VST meter jumps from 60 or 70% to the red zone, and remains there when I attempt to open a plugin’s GUI.
My Cubase is running the new 64bits precision audio engine. I’m using a Focusrite Scarlett 2i2 2ndGen. The driver is up to date and running at 1024 latency for mixing tasks.
This issue is graphics related for sure, but I don’t know what to do to solve it. Time to go for a new more powerfull laptop perhaps…
