I'm getting the same error message about the "edterrain.dll" as the faulting application. I can run in Instant Action, but when I run a single mission, and I've tried them all, the game crashes right at the point when it should go to the flight screen. Load bar is about 3/4 of the way across.
I am running windows XP Home Pro, SP3, GeForce GTX 260 with the latest drivers, June2010 Direct X. I will follow up with a crash log.
