First of all, you do not have to worry about this error if you update to the newest version of Cruel World before running the game.
If you haven't encountered the error, simply update the game and continue worry-free.
If you have encountered the invalid savedata error I may be able to help: I need to know your username and I need to know how to contact you.
Send me your in-game username (the one MINEd on terminals) and a way to privately contact you (i.e. twitter DM or email address) via any of these methods:
