I recently loaded up a flight in my brand new shiny Alphasim Blackhawk and i was flying at night in the spring with a major thunderstorm going on. Anyway i took off while battling the winds and lightning and rain. I got about 2 minutes in the flight and all of a sudden a pop up came up that said fsx must close and windows was checking for a solution to the problem. Needless to say i then closed FSX and restarted and tried to fly the same flight with the same plane but the same thing happened this and the next time. I am wondering why i keep getting errors. I can fly in normal weather fine but once i turn on that Stormy weather at night it likes to quit. I also have REX textures installed if that makes a difference at all. I would appreciate any input on this problem.
