Ok need a question answered please why after starting a flight in any ngx version the aircraft was running and ready to go after 2 months of using it tonight started up the sim loaded my favorite ngx and it not running none of them 600 700 800 900 why would this happen all of a sudden, thanks.

Are you getting any errors popups or notifications in the logfiles?You could try system restore if still enabled on your PC

Why would I do a system restore which never works anyway because 737 is not running when I start new flight, its the ngx not operating system thanks

Best guess is you installed something recently and that caused the issue your having.Did you try loading one of the default profiles? If so what happens?

I think Jude's suggestion was to eliminate the possibility that a change to your system (Windows Update, new graphics drivers, etc.) messed up something. Other than reinstalling, I can't think of anything based on your description.

Thanks guys you know a new flight software was just loaded hint hint not sure why that would conflict tried start up states also no go I guess the easy thing is to uninstall such said software lol which was a waste of time and reinstall NGX, thank you All.
