Animamundi- Dark Alchemist game keep missing!

Right. I downloaded the English version, patched the decensor patch I got to show the censored images in the English version. So my problem is....

After I reach the Demon in the Church chapter, I close the game to let my computer a rest. After I a few hours, I run the Animamundi game back. Guess what?

My saved data disappeared, lost without any trace! Including the graphic, the music, the alchemie; everything turn back like it used to be before I play the game; empty! And it happened twice!

Got any idea how this is happen? /stressed out

Thanks in advance.

where do you save your files??
