Hi everyone.

Problem:
Game crashes at startup or reaches menu screen and crashes then without an error message.
Installing new drivers and/or UE4PrereqSetup_x64.exe does not help.

I ran into this problem and I was able to solve it this way:

Everspace.exe and RSG-Win64-Shipping.exe changed to start in admin-mode
add an exeption in your firewall for Everspace.exe and for RSG-Win64-Shipping.exe

You can find that second exe here: Everspace\RSG\Binaries\Win64\RSG-Win64-Shipping.exe

Hope this helps
