Deleted my AC2 save file off of MU, anyway to get it back?

This is what you get for being careless. :( 
Is there anyway to retrieve it, or am I S.O.L?

I don't know but luckily the game is awesome enough another playthrough.

whats MU? and i take it you're playing PC cuz of your alignment color ? 
 
i formatted the computer recently, re-installed the game and my progress was saved on the Ubisoft servers so.. as long as you're logged in with the same Ubi account, u should be fine i think.

Time machine?
