I got it!
I installed CbB on my new laptop. And noticed I was missing a lot of Sonar Platinum plugins.
At first, I managed to find a ton of installers on my old pc.
For them to run/install, you need to have the original Sonar Platinum installed alongside CbB.
So I did that, installed Platinum (had the installer). Installed all sorts of stuff, LP Limiter, LP EQ from my old installers.
However Adaptive Limiter is part of Sonar's 2017.05 update. I installed Command Center, and voila. It allowed me to update Engineering FX Suite.
So I now have Adaptive Limiter again.. Since everything installed for Sonar Platinum, automatically becomes available in CbB.
