My Contact List is Missing in Eudora 7.1

Hi,
Yesterday afternoon, I have experienced an operating system crash and replaced the faulty operating system with Windows XP. Previously, I was using Eudora 6.2 as email client and now I installed newer version Eudora 7.1. After installing newer version, I have replaced all the folders and necessary files from my old Eudora setting folder.
I get back every feature perfectly except the contact list. There was more then 500 address in my contact list. I thought that I would get it fixed by installing previous version again and do so. Bad news is contact list is still missing.
Please help me, I don’t want to type all the addresses again.
Thanks.
