Alright, so if I get this right, after the end of each chapter when it asks you to save/load, you click load, and that's when you get the error?
You do not get this error when you boot the game up and play as usual?
At the moment, I can't fix it for you (version 1.5 will not have this issue), however since it seems to happen after you finish a chapter and save, my suggestion would be to only save in the main menu settings instead. So at the end of a chapter, when it asks you to save/load, click cancel. Then, when you're in the main menu, open the settings and save there instead. That should work.
