Flightplanner

Hi AllStrange problem.The way I set up a flightplan is generate FP from FSBuild which generates a plan with the extension .pln.Boot up ASX and select the flight plan and enter it in the briefing menu.Boot up FSX and click onto the Flightplanner and load the FP.I have generate hundreds of flight plans using this method with no problems.Today I generate a flight plan from Vancouver British Columbia to Lax.When I clicked onto the flightplan when in the Flight planner for FSX it would not recognized the flight plan with the departure airport CYVR (Vancouver).I could generate flightplans using CYVR as the destination airport, but not as the departure airport.I tried numerous plans which I have loaded in the FSX file with no problems.Has anyone else experienced any problems with CYVR as the departure airport.I could manually select CYVR and KLAX and it would generate a flight plan, just wouldn't generate the plan from FSBuid.Any comments appreciated.Kenny G.Vista Ultimate, Duo Core Nvida 7950 Acceleration.
