Shogun 2: Total War Cheats
Good work with the trainer though...
I have a collector's edition steam version on X64 win 7...
Not exactly a problem: but at one turn my pieces/armies on the map (the little soldiers that you move around) no longer had textures! They were just completely grey, this problem resolved itself after a simple restart of the game, though.
If it happens to many times the game is tricked into thinking its a illegal copy. I managed to fix mine by reinstalling but it can also be a issue with the steam server not giving you your licence key properly.
