Are you referring to your contacts in Outlook Express? Came across this piece of advice that may be of help to you.
"f you still have e-mail access for the old computer, open Outlook and click on the Contacts icon. Click on one of your address cards and then press Ctrl + A to select them all. Right-click one of the highlighted cards, and select Forward items. That will put all of your address cards as attachments into a new e-mail message. Send that message to your new computer. When you receive that message on the new machine, click on one of the attached address cards, and then press Ctrl + A to highlight them all. Move that window to one side, and then drag and drop those cards to your Contacts icon in Outlook."
I haven't tried this myself as I don't use Outlook Express but it just may work.
