I was doing a long cross country flight in Manfred BT-67 and 20 minutes before landing the flight sim crashed. I looked in the windows log and it pointed to fsui.dll, any one come up with a solution? The flight sim is stock with acceleration with the following add on's: Tinmouse II 737-200, Active Sky Evolution, Nvidia Inspector, Aerosoft Twin Otter, C-47 v2, C-117D v2, BT-67 v2.
