Sounds like it could be a corrupt file. Try downloading and running the freeware utility- Filemon in the back ground while you are flying. It will catalog all files that FS9 is running. Check to see the last files accessed by FS9 before the crash. This will give you a good idea where the corruption is. Just replace the files that you suspect are causing the problem.Here a line to Filemon:http://www.sysinternals.com/Utilities/Filemon.html
