I have KORD/KJFK/KLAX/GSX2 installed with status installed and active.
If they are flagged as Active, it means everything is working from the software side.
None of them work correctly: scenery partially/completely missing, GSX2 just doesn't work, Couatl will not restart/rebuild.
Couatl will always restart and rebuild, if you have the latest update installed.
I also get messages saying products are not activated (on P3DV5 startup) when they show as activated within the add-on manager.
Do they showed as Activated in a PREVIOUS session, but you are getting those messages on another startup of the sim ? This is consistent with the problems which were happening on our *first* release of this update, because Couatl couldn't read an already made airport cache and in that case, it didn't closed correctly, so it didn't work on the next startup of the sim.
Even when we HAD this problem, it was always fixed by removing the airport cache before each start but now, with the current update, is no longer required, since the cache will always be rebuild in any case.
So, again, from your description of the problem, it really seems you don't have the latest update. As I've said in previous posts you can check the timestamp of digital signature of the bglmanx65.dll, to be sure you have the latest version. It must be today, because that's what refresh the cache rebuilding at each start.
