Using the CS 767-300 on a flight from Frankfurt/Main to Ataturk I got a message reading "fatal error,FSX will now close" (or something similar). It happened just after I started the decent to Ataturk.The following is the readout.Does this give any clues as to why I have the problem? Any advice will be most appreciated. * Exception Text **************System.Runtime.InteropServices.COMException (0xC000014B): Exception from HRESULT: 0xC000014B at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at Microsoft.FlightSimulator.SimConnect.SimConnect.ReceiveDispatch(SignalProcDelegate pfcnSignal) at Microsoft.FlightSimulator.SimConnect.SimConnect.ReceiveMessage() at rexwxengine2.controls.ucLoadAircraftLocation.DefWndProc(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.UserControl.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)************** Loaded Assemblies **************mscorlib Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5448 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll----------------------------------------rexwxengine2 Assembly Version: 2.5.2010.38549 Win32 Version: 2.5.2010.1027 CodeBase: file:///F:/REX/Real%20Enviroment%20Xtreme%202.0/rexwxengine2.exe----------------------------------------System.Windows.Forms Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5446 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll----------------------------------------System Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5447 (Win7SP1GDR.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System/2.0.0.0__b77a5c561934e089/System.dll----------------------------------------System.Drawing Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5420 (Win7SP1.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System.Drawing/2.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll----------------------------------------Microsoft.FlightSimulator.SimConnect Assembly Version: 10.0.61259.0 Win32 Version: 10.0.61637.0 (FSX-Xpack.20070926-1421) CodeBase: file:///C:/Windows/assembly/GAC_32/Microsoft.FlightSimulator.SimConnect/10.0.61259.0__31bf3856ad364e35/Microsoft.FlightSimulator.SimConnect.dll----------------------------------------msvcm80 Assembly Version: 8.0.50727.6195 Win32 Version: 8.00.50727.6195 CodeBase: file:///C:/Windows/WinSxS/x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.6195_none_d09154e044272b9a/msvcm80.dll----------------------------------------System.Xml Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5420 (Win7SP1.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System.Xml/2.0.0.0__b77a5c561934e089/System.Xml.dll----------------------------------------System.Configuration Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5420 (Win7SP1.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_MSIL/System.Configuration/2.0.0.0__b03f5f7f11d50a3a/System.Configuration.dll----------------------------------------System.Data Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.5420 (Win7SP1.050727-5400) CodeBase: file:///C:/Windows/assembly/GAC_32/System.Data/2.0.0.0__b77a5c561934e089/System.Data.dll----------------------------------------************** JIT Debugging **************To enable just-in-time (JIT) debugging, the .config file for thisapplication or computer (machine.config) must have thejitDebugging value set in the system.windows.forms section.The application must also be compiled with debuggingenabled.For example:<configuration> <system.windows.forms jitDebugging="true" /></configuration>When JIT debugging is enabled, any unhandled exceptionwill be sent to the JIT debugger registered on the computerrather than be handled by this dialog box.

SimConnect is not eing able to handle data passed to it ("marshalled") from the REXX weather engine when REXX tries to load the local weather for Ataturk.See if turning REXX weather keeps you from crashing.General indication: Make sure your Windows Update is enabled so your MSVC and .NET runtimes can all be updated, and make sure you have the latest update for REXX (as it would seem REXX is the originator of the problem).Cheers,- jahman.

Thanks jahman, will do as suggested and report back.
