Names in the To or CC field are not recognized when I sent email, even if
they are in my Contacts folder.

I had to re-install Windows. I copied my mail file from a CD backup, and I
copied the Contact folder. I don't remember the filename or location (it was
a few months ago).

I can see all the names when I click on the Contact folder. But the names
don't get translated into email addresses when I send email. Also, if I click
on Tools Address Book, I get the following error:

The address list could not be displayed. The Contacts folder associated with
this address list could not be opened; it may have been moved or deleted, or
you do not have permissions.

How can I fix this problem?

Thanks,
