Now that is a nightmare.
I can't help you on this, but what has happened to you makes it all the more important to have more than one backup.
I'm probably paranoid. Apart from acronis backup, I also save all my stuff on an external 320GB HD,DVD'S, and backups are on all my other PC's and Laptops.
So although this doesn't help you now, It would in the future.
I hope you can retrieve your items, and no doubt someone here can point you in the right direction.
