After planning an IFR flight between O'Hare and the Quad Cities airport, I get the following error while loading the flight.Unable to load flight plan.Then, to be sure, after the flight loads and I am sitting at the terminal, I check the GPS to make sure and no flight plan loaded. I then end the flight and get this error message.Unable to unload flight plan.I have deleted the plan directly from the myflights directory, then try to recreate the plan and still get the same error.Now, when I reverse the flight plan and fly from Quad Cities to ORD, I have no issue. Same with planning and flying any other flight to/from ORD.Any ideas??

You might try replacing your gps.gau file in your fs2002gauges folder with one from your CDs. It may be corrupted. Use an unzipping program, search the *.cab files on the CDs for the gauge, and extract it to the folder noted above.

Guess I am not too sure that is the issue. Since I can plan and fly any flights anywhere else but from ORD to Quad Cities (can plan and fly the reverse route), it really seems strange.
