The following problem has suddenly arisen. After entering the departure and arrival airports and selecting "find route" I am suddenly returned to the desktop and FS9 is unloaded.The same thing happens whe I try to load a previously used flightplan.Any ideas on what this may be caused by, and what the solution might be?It would be nice not to have to unistall and reinstall the programme plus extras.Thanks in anticipation.

First, rename your fs9.cfg file to fs9.cfg.OLD. Restart fs2004, let it stabilize, then try making a flight plan and save it. If you still have the same problem, delete the new fs9.cfg and rename fs9.cfg.OLD to fs9.cfg.Second, did you move your My Documents folder from it usual place on your computer.For Win98/ME - C:My DocumentsFlight Simulator Files also could be have a user name in the list.For WinXP - C:Documents and SettingsMy DocumentsFlight Simulator FilesW.
