Any ideas?

[fencible]

Great game, when first installed, I can now fly all aspects - quick flights, training, campaign - but after quitting, the next time I start up CoD, it freezes as soon as I take off, or never completes loading scenarios and freezes at the 90% loaded mark. I have to kill the Launcher.exe process to get out of it.

If I uninstall and re-install (which takes many hours with Steam) - it works again.
My system is above minimum spec - dual core 3.0 GHz intel cpu, 4 GB ram, MS XP SP3, ATI4870 with Gig ram, Saitek X52 stick, CH Pro pedals.

Thanks for any help,
Fencible
