Stuck on Re-Install OL 2003

Hoping for a little hint on a problem.
I'm testing backup / restore, and am having problems with Contacts.
I'm about to do a clean install with a computer running Outlook 2003 at
home. I have a second computer for testing backup.

I've read some links given here recently.
I've saved my pst file to hard drive back up.
On a second computer that also has Outlook 2003, I replaced the pst file
with this backed up pst file.
Restored pst file is not read protected.
Mail is being sent to this one and only file.

All seems fine, except for Contacts. The contacts are all there, but when I
go to compose a message, I get a message that says...
"The address book could not be displayed....It may have been moved....etc.

If I do Tools | Address Book, I get the same message.

So...I can see all my contacts, it's just that the program is not using the
contacts in its pst file.
I've got the clean install on hold till I figure this out.

Thanks for any hints. I can't seem to find any related articles...
