I have enabled Mods under gameplay and restarted the game, and steam.

I am only trying to test other mods off the workshop, not my own.

I have the game via Steam, and cannot find the 'prefs' file anywhere on the drive, let alone folder. But as per point one, I shouldnt have to set it to '1'?

I have only the basic paid-for GC3 game, not the Crusader / other DLC add ons. Are those perhaps needed?

I simply cannot see any MOD's I download. None of the new Civilisations and none of the ships. Cant find a single forum hinting at what Im missing.
