Hi chaps. I have validated my game files, installed the latest graphics card drivers, reset the game settings, reinstalled DirectX and that other exe as mentioned here https://support.stardock.com/space/SHC/1370587141/GC4+Game+Loading+Issues and renamed the GalCivIV folder. I have the latest Windows Updates.
I'm not knowingly overclocking anything. All my other Steam games load okay. Only this one does not, it gets to the main splashscreen, then CTDs.
Debug.err pasted below. Thanks for any help!
