Joe,
Thanks for replying. The software doesn't provide Juno as an option and Juno does not have any export feature at all. So I can't see how Dawn could help, because it's looking for a CSV file, or Outlook, or PAB file etc. All I have is my address book on the Juno email website with no way to export it as Juno has replied that they do not have an export option.

I don't know what to do from here. I appreciate your attempt at helping though.
