Internet Fax Cover Page Fields not AutoPopulating

Searching for Internet Fax in outlook help finds no relevant entries. However
an Internet Fax company has just told me about the internet fax integration
feature of office 2007.

I downloaded and ran an executable from their website that reportedly
modified the registry to work with their service. Now when I click on
internet fax the body of the message looks like a fax cover page with
numerous fields. But after selecting a recipient only 2 of the fields on the
cover page (company name and sender name) are populated. All of the other
fields appear as "Type recipient name here" etc. Shouldn't all of these
fields automatically populate?
