Pardon the long explanation I'm just trying to give as much info as possible so I can get to the best solution -
I had bought the entire season of Walking Dead for my Mac during a steam sale a while back and was able to play the entire game through with no problems. This was a while ago. A while later I saw that the 400 days DLC was on sale and decided to buy that too.
Upon downloading the 400 days DLC I went to load my completed game and saw that it left me off at episode 3, NOT episode 5.
I ignored this odd fluke in my save file and decided to simply delete my old save file and just play the game over from episode 1 wanting to refresh my memory of the story anyway since it had been a while since I last played.
My first problem was that upon loading episode 2 a warning popped up that rewinding the episode would cause my choices from later episodes to be erased, which was impossible since I had deleted my old save file and was starting over from scratch. Then loading episode 2 resulted in a black screen with nothing loading.
After uninstalling and reinstalling the game didn't fix the issued I looked around on the forums I was able to fix this by copying and pasting the ep02-ep06 folders from the "pack" folder located in my "local files" folder into the "pack" folder in the walking dead game app itself.
Episode 2 ran perfectly after that, but now every time I try to run episode 3 the game crashes.
I'm not sure if it was the DLC or from upgrading my OS (most likely the latter?) that is causing these problems since I had played the game through once already with no problems whatsoever.
Any help or suggestions would be greatly appreciated!
