Cannot Retrieve Address Book details from a Backup

[Yossarian]

Hi.
This is my first post here, so please bear with me? I have searched, unsuccesfully, the forums here for an answer and also lived on Google for the past 2 days, also without success.

I am running Mac OS X Tiger. A friend wants me to retrieve all of the data from an Address Book Backup sent her on a CD from abroad. Nothing I have done works!
The size of the Backup is 5.6MB.
I have created a new account for the purpose. With Address Book (AB) open, File > Revert to address book backup gave only 2 card entries, one being the User and the other the Apple Mac welcome card.
After trying many other things, here is what I finally did before posting here ....

Showed the contents of the Backup file.
Copied the Metadata (size = 2.5MB) folder to User>Library>Caches>com.apple.AddressBook
Copied the following files to User>Library>ApplicationSupport>AddressBook:
AddressBook.data
ABPerson.skIndexInverted
ABSubscribedPerson.skIndexInverted
AddressBook-v22.abcddb
Copied the folder "Images" to the same location.

Those were all the files within the Backup.

Restarted the computer, repaired permissions etc and opened Address Book. Still the same 2 cards as before..

Can anybody please tell me what I am doing wrong and why what I have done doesn't work?

Thanks for your help.
