My PC crashed while playing Assassin's Creed Brotherhood and when I try to load the game, instead of saying the name of the file it says "Damaged save game".

I was at the 6th sequence, >80% Rome rebuilt, all missions were 100% synch. I lost more than 16 hours of gameplay and I'm mad and sad.

Is there any way to repair it? I have an i5 4670k and a 7870XT and it shouldn't be because of the computer. I don't want to download saves on the interenet, I want my save with my progress....

How can I contact Ubisoft? Maybe they can repair this damaged save...
