Hi Umberto,
I'm still having problems with KCLT. I bought via marketplace. Today I began a flight from KATL to KCLT. Twice MSFS froze up during the loading stage. My only recourse was to close down MSFS via the Windows Task Manager. A third attempt using the same flight plan, the game froze in mid flight. Out of ALL my airports, bought via market place or 3rd party, KCLT seems to be a star culprit. Please fix it.
