I know this is known, but if i load JFK or GSX my FSX crashes. The scenery will not appear and then the whole program crashes. I click on the addon manager and the fsx crashes too. It was working well (JFK and GSX,) , but then i had to uninstall them and when I reinstalled they crash. the whole FSX program. Fsx works with the default scenery at other airports. It all started when i uninstalled the QW 757. Everything was fine until then. HELP! please.
