So, was playing Crysis 2 on xbox today on Terminal with some mates. After the match was finished, I was about to check out my rank on the leaderboards but suddenly all my progress was gone.
No kills/death, never activated killstreaks, no distance travelled, everything is set to 0, except my precision and XP

I′m screwed :S

EDIT: Well, not everything is gone. I only can′t see my progress on the uuh... on a certain tab, in german it's called 'Agentenakte' should be something like 'Agents act' in english. My original scores are still existing. And I also can re-do all challenges, they′re all unlocked, I don′t know if I get XP by finishing them.
EDIT2: Looks like 'the new progress' I make doesn't apply to the Leaderboards.
I still have 300 games,145 wins, 150 losses etc...
EDIT3: I think I′m giving up this game... Now EVERYTHING except my XP is gone, it′s like a reboot now, just without prestige... -.- PLEASE! Are there any backups ?! I don′t want to restart everything
