This is my first time playing Heavy Rain and just this morning, I stopped at the part where Madison visits the Blue Lagoon club. I resumed the game this evening and to my surprise, the game starts all the way back at the beginning. All my completed chapters and unlocked bonuses are missing and the only thing that is still present are my trophies.

What happened? Is this a glitch? Has anyone experienced this before? Is there a way to retrieve the saved filed back?
