Sorry, let me explain in more detail:
I had all my products installed and they were working perfectly. Then I started getting messages when starting P3D for the first time since a shutdown/restart 'The product 'FSDreamTeam ...' is installed but not active on your PC. Do you want to activate now? This was for some of my products, not all. When the flight loaded, I was not able to start GSX. SHIFT+F12 did not work, I could go to the menu and select GSX and show GSX controls, but that did not work as well. If I opened the addon manager, GSX is listed as 'in trial mode' but if I clicked on register serial my serial was already entered in the box. If I loaded a FSDreamTeam airport, no objects were showing. Once I exited the sim, the licence wizard opens and asks me if I want to activate or deactivate licende for certain products, but for all of them it is listed that my licence is valid.
I tried unistalling/reinstalling every product, running the updater a few times, but nothing helped so far. It has happened before that GSX did not want to start, but a restart or update always solved that, but in this case I have not been able to figure out what might be the problem by myself.
