Thank you for your answer.
The aircraft seems properly activated, and my license is confirmed each an every time I launch the sim.
I only have basic controls, yoke, quadrant, and no external avionic.
And once reloaded, I fly the lady without any problem.
If you need logs or pics, I may of course provide.
Anyway, this is my preferred plane, and I do hope that, coming X-Plane 12, an updated version will be available.
