Somethings happened which I seem to recall there was an explanation a while back. When I load the Flight 1 ATR my computer then does the standard load of the sim but stops at 77% and then crashes and the usual "do you want to tell Microsoft" box appears. Anyone any ideas?Kev

Just discovered its not the Flight 1 ATR it happens every time I start Flight Sim - seems to hang for ages at 77% loading then thr dreaded Crash.Kev
