I tried to export them as a CSV file, but it gives me an error saying it could not be done.
The farthest I get is choosing what data I want to export (First Name, Email, Work #, etc...) -- this is after choosing where I want to save it as and as what. Then I hit finish... which takes me to a screen that says: "Error exporting the Address Book"
Any solutions?
I am doing exactly what csamuels is saying:
"file | export | other address book
pick comma separated values."
