Exporting and importing are never the correct way to transfer Outlook data.
You have lost a lot more than just your address book, but you can at least
restore the address book easily. Method has been posted here countless times
and is well documented in the KB.

I have exported my Outlook stuff on the old PC, moved to a new PC and
imported the data here. Everything works - except when I start on a new
email, and click the To: og CC: buttons. I get an error (in my native
language, translated as accurate as possible): "The Address-list could not
be
shown. The folder Contact Persons, linked to the Address-list, could not
be
opened. It may be moved or deleted or you do not have sufficient rights.
You
will find how to remove the folder from the Addressfile (?) in Outlook
Help".
However, I may click the button Contact persons in the lower left corner
in
the main Outlook window. All my contacts are still here and I may start
new
mails from here, selecting the recipient from here - but it is more
tedious.
I'm on the newest XP PRO and Outlook 2003 (11.8118.8107) SP2.
