Game is carrying and now all my data is corrupted

I've lost all of my data ! I spent many weeks on it, give my data back. The game keeps crashing on start up screen and an error with corrupted data alert keep appearing !

I haven't been able to play all day. It either crashes shortly after start with an error saying my graphics card has been removed, or it will let me join the queue and then just kick me to desktop when I reach the end of the queue. Played for a few hours yesterday, but not today.
