I am running P3dV4 and I have attempted to do a flight several times in the QW787 from Boston but after I get to my cruise altitude it always crashes to desktop. I went to my Event viewer and saw this:
Prepar3D.exe
4.2.21.24048
5a7c832c
ntdll.dll
10.0.17134.1
207580e2
c0000374

D:\Program Files (x86)\Prepar3D\Prepar3D.exe
C:\WINDOWS\SYSTEM32\ntdll.dll
635d3214-daed-4d46-82bd-b06d56453f06
Any ideas on how I can solve this issue?
