Save Issues.

Had a similar problem for one time, too. While saving R&R closed itself. After restarting R&R the savegame was not loadable anymore.
I think you have to restart the career. But better wait for comments of some other and more experienced users, maybe it's not completely lost...

But I have to say: That's why I generally have more than one save game and especially not just a quick save. You also should do that in future!
