Trying to run a plane that is not default or net. I get this error with the X Plane 10 demo. I downloaded the torrent demo. Does anyone know what the cause for this is? I know it is the demo, but if the demo does not work, then I doubt someone would buy the full version of the game. I would love to have a copy of it, but right now it does not look to good. I have a Dell XPS 17 3 GB graphics card, 6 GB ram and 8 processors i7. I can run Flight Simulator X on the best settings without any lag, so why this problem, something else? I managed to get into the demo once, but at my second try I had no luck, even tried several times more Am dissapointed in the new Flight so would like to convert over to X Plane 10, if I can
