I just had the same thing happen to me. Hours and hours spent playin down the drain. I was on the 3rd difficulty for the giant adventure and everything else was 100% complete. I am looking for a way to get a refund cause this is the last straw. I don't think I have had a save corrupt since the days of my PS2. If you could point me in the direction on how to get a refund it would be much appreciated.
