I would like to help you but are not entitled to, keeping in mind the copyright instructions from Steiner
Quote:
Your purchase of a website membership, or a CD-ROM disc, entitles you to use the stamp album page files for the personal use of you or your immediate family. This is the only use you can make of the files or CD-ROM discs. You may not use them in any commercial activity, such as selling pages printed from the files, or reselling the CD-ROM discs. Also, you may not share the files or CD-ROM's with other people, such as a group of friends or members of your stamp club, even if you do this without charge.
It's a 'grey-zone' because you have already purchased the CD before and then lost it. Maybe Steiner himself will be willing to send you the relevant pages for free when he has confirmed you have been a customer with him previously?
