I'm having a big issue and need urgent help!

I had a problem with my computer and the windows got complettly corrupted, so I made backups and formated.

I've recovered the wallet.dat from the corrupted windows before the formating, also.

Then, after formating, I've started the new client again, shut it down and replaced the new created wallet.dat for the old backuped wallet.dat.

The problem is that now my coins only appear as unconfirmed! And the wallet shows no connections and it has passed over 4 hours!

Please help, I've been keeping my spots for over 2 months and I don't want to loose all my coins in the deadline

HELP PLEASE!!!
