When I open up my address book, there is nothing there now. I've tried restoring both the Addressbook.data.previous and also taking both Addressbook.data and Addressbook.data.previous from my backup on my Mybook and there is nothing there. Why would this happen and is there anything I can do about it at this point? It was fine just yesterday. Thanks. Update: They are gone from .mac also. Update 2: I tried to synch them back on with my Motorola phone and it wiped the phone's address book. Now I'm really getting ticked. Is it this .mac synch that is doing it? Update 3: I went to my Macbook and printed them out (as an insurance policy), backed it up, then disabled .mac synching, synched the phone to it, and it wiped those out too. Shouldn't it be adding to each one instead of just wiping them out? This used to work just fine and I don't know what has changed, but it is consuming way too much time. I went back to my Mac Pro, added a test address, used iSync, and it didn't add to my phone (but at least it didn't wipe out the test address). Foolishness... Update 4: Whatever I add to the phone now shows up in my address book, but not vice versa.
