e-mails lost when opened Entourage database after installing Tiger


My basic question: E-mails located in user-created folders in Entourage for OS X are not visible after I clean installed 10.4 and tried to open the database in Entourage after re-installing it. How do I dig up these e-mails? They must be in there somewhere. I copied the whole HD in which my database was previously working fine and can retrieve preferences, etc. if need be.
