So I have been using .Mac to sync everything between my powerbook and iMac for a couple months now and suddenly my .Mac address book appears to have been wiped clean. When either computer attempts to do their regular sync with .Mac, they're prompted to delete all their contacts. Is there a way to tell .Mac that the address book on the local computer is the correct one and it needs to be uploaded to .Mac for syncing rather than have the address book with no contacts downloaded to my local computer? I'm completely lost on how to make this seemingly simple task happen. Thanks.
