I see. Yes unfortunately due to the structural updates I've made in the past few releases older saves are usually broken. Sorry about that. You can use the "skip ahead" feature when you start a new game to get back to where you were before though.
I started on the last update 0,69d, so my save is not that old.. I probably could start a new game, but I don't really memorized all my options throughout the game so it's a little bit unpleasant.. and if I will have same type of errors as I had on 0,69d, then it's probably something wrong with the game and not with the saves..
Sorry but yes the last couple updates did break saves because of some structural rearrangements. It may be possible to load a save from 0.69d and (after ignoring a few error screens) continue to play if you get to a new scene and Sparkle has a wardrobe change (a lot of variables depending on Sparkle's outfit).
