Fenix wont activate

You may be able to find some help in this feedback thread for the Fenix A320
https://forums.flightsimulator.com/t/released-fenix-high-fidelity-a320-discussion/417613/

However, it is a long read!

I, also, would suggest that you contact Fenix directly using your log in account on their website and file a support ticket. They would be the best people to try and fix your particular issue… if you haven’t tried this already!
