Recently I had a registery error problem cause a PC crash while exiting my games, I was playing Crysis 2 and went to exit and my PC crashed...

Everything is fixed now but I lost all the single player missions I unlocked and collectible items I unlocked in Crysis 2 SP...I lost all progression and everything...however strangely enough my saves are still there, as well as my last save(Resume Game)...ofcourse I haven't lost any MP stats because this is linked to my account....

Anyways, does anyone know how to get everything back, or is there some sort of code so I can get all the missions again, so I can choose which one I want to play....I don't really care about the SP stats, but being able to select any mission from the start would be nice....

any help would be much appreciated....thanks....

Almost identical issue was resolved here.
