I have the same difficulties. I've downloaded the new fiel on the website, extracted it, copied/pasted the previous save like last time... The game starts, but I can't click on "continue" that is grey tint, like if the game doesn't recognize the previous save.
In my numerous other tries, it happened the opposite : the saves has been recognized, but it's still asking me to wait for the chapter three's release...
I want to plaaay, help me T^T !
