I've dowloaded the latest demo today and have met two problems: any time I tried to save a file further than the first page, it would give me an exception , which fortunately I could choose to ignore, save and keep playing, but after day 42 anytime I try to save it gives an exception I can't ignore, making me unable to save the game. Please take a look into it. I could send you the exception log in case you need it.
