How do I reinstall my old Contact Files (on c drive) after reinst.

I had to reinstall Outlook 2003.. I ge this border on the top that reads "
Finalizing Installation".. Caught the bagle bug last week...
McAfee Deleted the c:\windows\system32\winshost.exe file

Transfer of contacts from MSN was successful, but how do I retrieve the old
files from new contacts made in Outlook? They seem to be still on the c:
drive... \local settings \ application data\Microsoft\ *.ost.

Your help is appreciated.
Thank you.
