I worked halfway through episode 4 last night, only to try to launch it again and have it corrupt the save. I did some research and found out about this file called prefs.prop and how it's saved in two locations instead of one all the time. Anyways. I just copied prefs.prop from
C:\Users\****\Documents\Telltale Games\The Walking Dead\prefs.prop
~\Steam\steamapps\common\The Walking Dead\Pack\default\prefs.prop
and everything loaded up fine. I hope this helps someone.
