Bryan you’re a genius! The fault coming up in the Event View was;Faulting application fsx.exe, version 10.0.61637.0, timestamp 0x46fadb14, faulting module FS2AUDIO.dll, version 0.0.0.0, time stamp0x4bb01ad3, exception code 0xc0000005, fault offset 0x0004e152, process id0xef8, application start time 0x01cc3e70eb0e1971. I did have Audials One (Tunebite) installed on mymachine. I took this off and reinstalledFS2Crew and it loads up fine. Do you think it would be safe to reinstall Tunebite nowor will the audio codex still lead to the same fault. I don’t use it often so it won’t be to hardto install as-and-when I need it. Cheers for all your help, Deaks P.S. Also found this in the Event Viewer. Do you know what’s causing it and is it aproblem? Failed to create restore point on volume (Process =D:\Flight Simulator X\FS2Crew2010\Misc\DXUpdate\DXSETUP.exe SimulatorX\FS2Crew2010\Misc\DXUpdate\DXSETUP.exe" /silent; Descripton = äx6v; Hr =0x80070057). No rush on this one! Deaks
