OK, well at least you answered one of my questions! Now I know that you're using the Win/Linux version you DO need to install the bugfix patch, so I'll ask that question again, have you installed the bugfix patch? The link for the patch has now been moved out of the Installation spoiler to right above the Download links in the OP (hopefully that makes it easier for everyone to see). Nobody can help you until you start providing some information that actually allows us to help you.
As
TheDevian has said, it's not a good idea to use old versions of Ren'py and libraries. The game archive contains everything needed for the game to run, but if you're having to replace the included versions of Ren'py and libraries with older versions to get the game to run then there's likely something wrong with your OS. Try following
TheDevian's advice and start with a fresh install of the game, DO NOT replace the included libraries or Ren'py, DO INSTALL the bugfix patch. Try running the game, if the game loads then try to start a new game (just to see if it loads and allows you to start a new game). If that works then restore your save game and try loading it. Let us know how it goes, if you still have problems someone might be able to help you further.
I'm afraid I don't know anything about Linux, I've never used it, so I'll not be able to help you with any issues you may have with your OS install.
Might not work,
TheDevian has already told you that he couldn't load your save, so what makes you think you'll be able to load other people's saves?
