Save file lost

I kept getting these messages earlier today and i got a few Granite Error: 2000000 messages after i got booted to the main menu earlier today. Now i open the game and there is no save file, just says 'new game'. I am quite dissapointed as i was 100% done with the game on infamous mode ng+, and just wanted to play with my friend. Is there a way to restore my file, or can i download someone elses save file thats 100%? Any help is appreciated.
