missing contacts after uninstalling Outlook 2003

[Victor]

I recently evaluated a copy of the new outlook 2003 with
business contact manager. Before that I was using outlook
2002. I had a contacts category called business which was
ported over the business contact manager application.
after deciding that we did not need outlook 2003, we
uninstalled it and went back to outlook 2002. Now we cant
find all our business contacts. how do we get them back?
there are files on my pc with mdf and ldf extensions...
