Hello everybody. I am here due to the fact that I get a ctd everytime I fly for about 4 hours. I set up my flight and after about four hours the sim randomly freezes. I then have to the to the task manager and shut it off manually. When windows asks me to close the program or check online I click the little arrow with the details and I get apphangb1. Is there anyway to fix this or do anything about it.thanks steven

Hi,What are you flying, where, and do you have add-on scenery?Best regards,Robin.

It happens everywhere, with every plane. I have active sky x and x graphics, lds767, pmdg 747, super 80, gex, ultimate terrain x. I think thats it.

Oh and I already reinstalled.
