Have you already played chapter 1? You need to play that before playing chapter 2.
Download Release Chapter1 0.25 for win/linux or mac. You can find the links below
Thanks for posting that. Just to be clear, you...
1 Played chapter 1
2 Saved the game (save slot) when requested
3 Played part 2 (starting a new game)
4 Then, when you tried to load a save file, you got that error?
Did I get everything right?
If that's the case, there isn't an easy way to fix the problem, unfortunately.
But I can provide a few (working) save files. Just extract them, and put the files in the save folder. mediafire.com/file/t7e8h31b178pw8z/lffgsaves.rar/file
Sorry for the inconvenience.
