Hi latest version of the game won't start. (I was trying to start a new game). I have tried a number of the suggestions provided to fix things - but no luck. Verified files on Steam - Clean install of latest NVIDIA drivers - Norton internet security up-to-date - Any ideas please? - Oh - had a couple of very small mods but I have deleted those.
