I don't know what happened but when I tried to play the new version my save didn't appear I even found them in the folder but I don't know what to do to make it run
1. Make a backup of all those saves, and note their numbers.
2. Open up the game and make a save in every number slot that you have save files for.
3. Close the game, then replace those save files you just made with your backup saves.
After that, your save files should be usable again.
