Sorry if I'm being dim, but I've finally upgraded from my lovely old iMac G4 (running OSX 10.3.9) to a lovely new Mac mini (running 10.8.2). Wow. How do I transfer all my contacts from Contacts 3.1.2 to Contacts 7.1? The only thing v3 lets me do is save a .abbu file, and when I try to load/import that into v7.1, I see a message warning me that continuing will overwrite all my existing contacts (which I don't have, so no problem), but then nothing happens - no contacts ... Anyone able to help please? I have hundreds of contacts ... Thank you.
