I upgraded to Windows 8, but still backed up all of my save files. They're in the right folder (C:\\Users\Nick\Documents\Telltale Games\The Walking Dead), but for some reason the game will just not recognize them. When I start a new game, it will start saving over the old files (save_1, save_2, etc.), thus confirming that it's in the right folder. It's worth noting that I've since replaced those with the old save_* files, but it's still listing the new game I started to test it out in-game.
If I can't get this problem fixed, I'll either have to start again from episode 1, or start episode 5 with the default choices. Given how many choices I've made and how many hours I've put in to the game over the last four episodes, neither of those options sound attractive. Anyone have any suggestions?
