Retrieving Lost Data

[gameshoes]

So I was playing online...
Just got the kill 100 people with shotgun, and rifle achievement, kill 25 people on rope, become second lieutenant achievements.
Then Windows gives me a friendly blue screen of death.
So it resets and what not, everything seems fine.
Then I log onto the game, and it seems to take longer to load than usual.
Then once I'm in, it claims I just unlocked the achievements of getting Private First Class and Officer which I've unlocked long ago.
So I check the achievements and... ehhehehehe...
Those are the only two I have now.
Everything else... gone...
Even the unlock all weapons is gone even though I have all weapons (How ironic).
I have all of the equipment and experience still, just the ribbons or badges, etc are gone.
So is there a way to retrieve the lost data? Or am I screwed?
And if I'm screwed, is there a hack I can use to get back the achievements?
I know you guys will cringe at the word hack and I do to, but I wasted enough hours on this game and I don't feel like wasting them again.

I had absolutely the same problem two times http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif Blue screen and no more weapons and equipment for me. I don't care about my rank but I need my weapons for the multiplayer games http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif((
