Oh, how heartbreaking. Was it a multi- session burn to the CD or did you burn everything all at once? Have heard that multi-session burns may result in data loss. Is it just one file or all of them. There have been a few instances when PSE wouldn't recognize a PSD file but never did find a cause for that- Has happened to me a few times and have heard others say the same thing. ALso have heard it is better to save to R formats instead of RW. Sorry really don't have a solution- just asking more questions for you to answer so that somewhat more knowledgable can give a solution. I surely hope there is one out there for you.
