Hej guys! Searching for anyone that has had the same problem or ideas for a solution.
Not happened before, no changed settings. MSFS run on dvd.
The last 2 days i have attempted a flight of around 2hrs. (Not 100% havn´t got there yet),
but (now 4 times) MSFS has crashed after about 1.5hrs of flight! Same route and plane, on autopilot, de-ice etc. No warnings or indications, but MSFS just closes down! 
Any ideas of graphic settings i should reduce with the 1.5hr crash time factor?
Regards
Sean
If its the same route all the time, it is probably not the fact that it crashes “after 1.5 hours” but more that you then reach a point in your flightplan where the scenery or an installed airport AddOn crashes your sim.
It would be more helpful if you tell us what that point is where you crash and if there is an airport/scenery addon nearby that point.
Looks like you´re right!
My route is W77 - 0W3, FL120, IAS160
MSFS is crashing (closing down) when i reach 4 miles east of Andrews (KADW) Washington
Maybe there is an add-on/scenery here which is conflicting?
How can i check?
I have only MSFS Pro Deluxe updates.
