Hi guys Installed NGX last week and after a cursory look decided that until I am more familiar with the new aircraft I would continue to fly my Level D 767 for my virtual airline. The problem is that since NGX installation I can no longer use FSX for more than about 15 minutes without a CTD. Its just like a few years ago when Flight Sim was very unstable. I have had no problems, at all, with the stability of FSX since I installed it a few years ago, until now. Is anyone having similar problems and is there a solution. I am running Windows 7CPU i7 950 @ 3.07 ghz8 Gig ramNvidia GTX 570
