After messing around with the game for hours last night, I just could not get my save to carry on to episode 4. When I would start the game, episode 4 was installed and I could play it, but only with random choices because my save from episode 3 was not compleated even though it was before episode 4 was installed. After I would finish the last small part of episode 3 it would go to 4 but it would say Comming Soon for some reason even though it was already installed. I ended up fixing it today and thought I would post how incase anyone else runs into the same problem.
After copying the prefs.prop file from X:\Steam\SteamApps\common\the walking dead\Pack\WalkingDead103 folder and pasting over the one in the one in the X:\Documents\Telltale Games\The Walking Dead folder every thing works like it should now. All my decisions saved and are now carried over to episode 4 and everything works fine again.
I hope this saves somebody else from going through all the headaches that I went through last night.
