So I've been combing threads for a few days trying to find a solution but nothing yet so I thought I'd try here.
I'm playing TWD on PC (Steam) and am a good chunk into episode 3. Went to open the game the other day and I have no saved games available. Game starts right back from the beginning asking me if I want standard or minimal feedback on the gameplay.
The second option here is exactly what happened to me: https://www.telltalegames.com/forums/showthread.php?t=41676
I can see the saves in the documents>Telltale>Walking Dead folder (35 of them to be exact) but they don't load.
Ran the support tool and resulting file attached.
Edit: I should note that I only see one prefs.prop file for the game. It's in that same folder with the saves as noted above. I don't see a second file in the steamapps folder as been noted by some.
