I have version S2-C1-E11-B1.. does anyone know how the save files from my old version will work?? can i paste my saves from old files into new or even just overwrite the new and hopefully itll pick up my saves?? there is no 'save' fodler i can see

Yes, just paste the folder in there (inside the folder named "game"). The folder will be auto-created if it doesn't already exist. As for picking up saves, it will scan for this folder, as well the game's own save folder in your user profile (located under "%appdata%\RenPy" on Windows; that path should resolve to something like "C:\Users\yourusername\AppData\Roaming\RenPy" - every RenPy-based game has its own folder here). The game will use both save folders, though, and will use whichever file is newest if it exists in both locations. Meaning, if you've saved in the same save slot (in that particular game), it will use whichever of the two that was saved last.
Also, I believe your save should work, it's not too old.
