Hey everyone i have a problem with my flight sim. Brand new pc intel core i7 4 gb ram Ati 5830 video card.windows 7 64bit. Installed Fsx then sp1 then sp2 then installed orbx Ybbn manually added scenery files . Then installed Pmdg Md 11. Turned on flight sim cranked the graphics up got flying and was reaching anywhere from 35-100 Fps. At this stage i could not of been happier with Fsx. Then i went to the Pmdg website and downloaded the Qantas livery. Went to install it and it says aircraft.Cfg cant be located. So i go into the aircraft directory and the folder has dispareared so i thought that was odd cos i was flying it 5 mins before. So i went to load Fsx back up and a error comes up saying cant locate scenery file windows will look for a solution. Then Fsx closes down. Re start Fsx same thing. Is this as simple as putting the Fsx disk in and going for a repair. Any help on this would be awesome thanks in advance ben
