I have several FSDreamTeam airports as well as GSX. Yesterday when I started FSX I got an error message for each airport saying the airport is installed but not active. Do you want to ACTIVATE it now? I click yes, it asks me if I'm sure and I click yes. After going thru all airports the Free Flight screen comes up and I get an error message that says "Esellerate engine ERROR, code 0xe0010004 No engine is installed" for each airport I load the flight and go into the Addon Manager and it shows GSX and all my airports in Trial Mode. I click on Register Serial and try to re-register my airports and the addon manager just closes and it goes back to my loaded flight. After trial mode expires the airport disappears.
