For those who have the problem where their decisions don't carry over:
  
 -Possible Fix-

The game stores a "prefs.prop" in two places. One in: 

C:\Users\___\Documents\Telltale Games\The Walking Dead

And the other in:

D:\STEAM\steamapps\common\the walking dead\Pack\default

Or if you don't have the Steam version, its somewhere in your game DIR. 
Do backups before overwriting anything.

Copy the prefs.prop file from your game's DIR folders, and overwrite it in your Documents\TTG\TWD folder

Go in game and load the save game with your finished EP1. Switch to EP2 in the chapter select and run it. 

This worked for me when any other solution did not. My decisions carried over.
