FSX Hangs on start-up

Hi All,

Just before I go for a total re-install of Windows 7 & FSX, I might have missed something.

I have Windows 7 64 bit on a quad core with an Nvidia 9800GSO, saitek yoke, saitek radio panel. I run Ultimate Traffic II & FS Panssengers. I have Captin Sim 757 and Wilco 737 PIC loaded as well.

When starting FSX it loads all the module and then hangs. Task Manager says not responding and the only thing I can do is shut down the progam

I have removed the previous & saved flights as I know these can sometimes cause a hang. Still no joy.

I have renamed the FSX.CFG to FSX.BROKE so that it has to rebuild the FSX.CFG. I know this worked as FSX ask me to re-authorise the modules for the add ons. Still the same thing - stops just before the menu.

I have run a repair of FSX from the DVD's and reapplied SP1 & SP2. This has not improved things.

Windows is up to date and also the nVidia & Creative drivers are the lastest available.

Before I do a wipe and re-install does anyone have any ideas. The though of spending a day to doing a rebuild from scratch is not appealing!

Thanks

Mick
