someone could tell me what would it be the problem??many times during a session flight fs9 CTD with error ntdll.dll messagethanks

I can't comment specifically on this error as I've never experienced it. I have, however, experienced many C2D in FS9 until I stopped using the FS9 logbook. My procedure to restore FS2004 after a C2D was to delete the fs9.cfg file(located here: C:Documents and SettingsUsernameApplication DataMicrosoftFS9FS9.CFG)When FS9 is restarted, it will create a new fs9.cfg and it takes about another four-minutes to reset your former settings (which were deleted with the fs9.cfg file).[/font size]P.S. I had over twenty crashes-2-desktop in FS9 while using the Logbook. I have not had one since NOT using the FS9 Logbook. Now, is someone going to tell me it was NOT the Logbook causing the c2d?)P.P.S. The FS9.1 Patch MUST BE INSTALLED or one encounters scenery issues which also cause C2D[/font size]
