I install it , then use the configuration app to stack my gauges the way I want , I select my aircraft ? 310 R. Then save settings , and exit. I then use the ? app to select which avionics package I want (Navstax ) then save that. When I go to start the sim it looks like it wants to start ,splash page pops up , progress bar starts to move, then everything disappears. My prepar exe. Is open and I have to select windows task manager to close the exe. File. If I uninstall the Navstax the sim starts normal. Any thoughts or help would be appreciated . I was really looking forward to using the stack , looks great. Looked in the forum ,but not to many people there yet. By the way I'm running Windows 10 , Prepar 3dV4 Proffesional, ? 310R aircraft, and I have updated Navstax to version 180420
