I'm a bit further down the track with my FS9 crashes when it tries to start in the FSX demo area. Has a look at the error messages, its reporting a problem with terrain.dll. Its using the correct one for FS9, so I can only assume that the install has interfered in some way with the terrain data. I'm using FS Global, I might try switching that off for the Americas and see if I still get the problem. Frank T.
