you can save the game, i know that. but that is while you are playing the game. but if you save the game and quit, then restart it. it makes you start over? where is my save? does this happen to everyone, or is it just me?
Try playing the game as administrator, sometimes it happens, if it's like that check if you have all the save files in the right spot, usually when u update and you don't add all saved files it doesn't show old ones
