Howdy. I just royally fried ALL of my addresses in Address Book; my error. I thought I'd just open Add Book and re-type them, but when I try to open it I get a message "Can't use this w/ current OS system". What? I have been using it all along, so what happened? Too, I went to re-install Add Book from my original CDs, but it isn't listed on the one CD and I am afraid that if I re-install all OS files and software I will get the old OS and have to update it all over. Can I get Add Book somewhere so I can re-install it, or just fergit it and get a different app entirely? Quite lost here. Thank you.
