Thank you very much for diagnosing the problem!!! I ran fs9 using three default aircraft - C172,C182 and B737 uing the default flight (Seattle AP takeoff). Same error in all caes. They mut all be using the same default gauge. Any hints which gauge? Ken

Here it is. It appear to have somthing to do with the aircrat air file. Whichever aircraft that is set to the default flight appears in the log file. ********* FSUIPC, Version 3.65 by Pete Dowson ********* Running inside FS2004 (FS9.1 CONTROLS.DLL, FS9.1 WEATHER.DLL) User Name="" User Addr="" FSUIPC not user registered WIDEFS not user registered, or expired Module base=61000000 ClassOptions: UIPCMAIN=FF7F, FS98MAIN=FF7F, FS2KMAIN=FF5E WeatherOptions(Orig)=0000B027[0000B027] InitDelay: 0 seconds WeatherReadInterval=4 LogOptions=00000001 DebugStatus=0 15078 System time = 16:54:48 15078 \\KW-GAME\E\Program Files\Microsoft Games\Flight Simulator 9\ 15078 System time = 16:54:48, FS2004 time = 12:00:00 (00:00Z) 15281 Client Application: "fs9" (Id=2368) 15281 E:\Program Files\Microsoft Games\Flight Simulator 9\fs9.exe 15281 Product="Microsoft Flight Simulator 2004 - A Century of Flight" 15281 Company="Microsoft Corporation" 21953 Illegal read attempt: offset 0238, size 3 [P2368] 21953Program or module not accredited for use with this unregistered FSUIPC 44562 ### IPC Message processed in 22609mSecs ### 104578 FLIGHTS\OTHER\FLTSIM.flt 104672 AIRCRAFT\c172\Cessna172SP.air 105500 Clear All Weather requested: external weather discarded 114047 System time = 16:56:27, FS2004 time = 16:56:20 (23:56Z) 114047 *** FSUIPC log file being closed Memory managed: 805 Allocs, 805 Freed ********* FSUIPC Log file closed ****

I will try to end the log file again.. I hope you receive it thi time.

I re-intalled fs9 on a new PC and then downloaded FSUIPC 3.65. Now fs displays an error about running programs that are not accreditd for aces to an unregistered copy of FUIPC. WHat does this mean??????
