Your post is confusing.
Once can never open a PST file from a CD. It must be on a hard drive and
have its read only attribute removed.
However, the error you are reporting suggests you are also trying to use a
PST file created in Outlook 2003 in an earlier version. Are you? What's the
entire story here?

Sorry yes you are quite right, I have now copied the back up to my hard
drive and I have been able to open the backup successfully. However this
backup is a couple of months old now and I have created many new contacts and
updated some others since so I will still have to filter through and choose
which contacts I want to copy so I think this defeats the object of making
the job simple.
The backup from my old computer is from Outlook 2000, my new computer has
Outlook 2003
Is there a find and replace option or somewhere where I am add the "+" in a
dial option? Otherwise I may just be better off amended the telephone no of
each contact

Outlook has no search and replace. For static data fields you can export to
Excel, do your find and replace there, then import back but that usually
does not work for the derived fields like your phone number fields or File
As... field.
You can set Outlook to automatically add the country field to local numbers
in Outlook's dialing options: Contacts > Actions > Call Contact > New
call... That preference will only apply to newly created contacts, not to
existing or imported Contacts.
