The above image is what I was getting before even though I had completed all episodes as well as 400 Days on Steam before trying to play Season 2. I found out that this was probably because I had to play Season 1 in Windows compatibility mode because the game would not launch through Steam otherwise. I had tried booting Season 2 through compatibility mode as well to no avail and, through trying various things, it seems I've lost my original save anyways and I'm gonna have to play Season 1 all over again before starting Season 2. Really frustrated about this.
Anyone else experiencing any difficulties or inconsistencies regarding saves? I know there are also some server issues people are apparently having and that the game's claiming that some "don't own the game" even though they do.
