Sorry, I tried this and it didn't work. I tried disabling Nortons360 firewall and auto protect but AS16 still crashes. I get the log error while FSX is loading and then get the fatal AS16 error about 30 seconds after FSX is fully loaded and the sky graphics are running. Question. While running AS16, what should the fsx weather settings be set for? I have noticed that when I set the FSX weather to real world settings, I get an error that "an error occurred while downloading real weather data. please make sure your internet connection and configuration and try again" It's strange that I can fly on VATSIM but realweather can not download.
