Recently I bought "The Walking Dead" (all episodes) through Steam.
I finished the first episode. Then I started to play the second one and I found that my decisions don't influence game at all. I read this post. I copied the file "prefs.prop" from Steam folder to "My documents" folder. It helped.
But when I started to play the third episode the problem appears again. Clem suddenly says that I don't tell her about the murder of senator. But I told her everything in first episode!
I tried to copy file "prefs.prop", but it doesn't help.
I don't understand why Telltale Games does nothing about this problem. I paid my money and I want to play game, not to rape my brains how to solve the save problem.
