it works if i download it myself here and place it in the "renpy" folder, maybe you got the wrong folder or renpy blocks it for being from another pc? i can just make a vid of me deleting it using microsoft visual studio so you do it yourself while watching it.
you can also delete only the faulty save from outside (from the saves folder AND the hidden appdata one on your pc), if you haven't deleted everything already... if you used more than a single save, of course, always use your empty slots just in case of shit like this, they are infinite!
