Nokia Nseries :: Erased Contacts When Updating N8 To Belle?

I have updated my Nokia N8 to Nokia Belle with Nokia Updater for Mac but I cannot find contacts, sms and notes. All disappeared and unfortunately I don't have a backup. It is urgent and important. At the end of the update it was asking me if I wanted to import contacts from another Nokia phone, but as it wasn't the case, I bypassed that option. Surely I did something wrong but I really do hope that contacts, notes and sms are saved somewhere on my Mac.
