I have shot using a P25 with CaptureOne Pro and DB for the last year without any file issues. Then, last week I was working in DB on a friend's Powerbook. I shot all day and the files would continue to function properly. Now a week later, after having transfered the files to my own Imac G5, the sessions will not load. And not all of them, only 4 of 12 are unable to open. I have attempted to open them in other image software. I have tried renaming the files and session. I have dumped them individually into new folders. And still, when I attempt to add the session, I receive a prompt reading: "Could not open the selected session file. Possible reasons include the file being unreadable or having an invalid format."
When I access the folders in Finder, the images are present, but only the generic Preview thumbnails are there. I have also tried opening each individual file in C1. The file loads and creates a blank box in the thumbnail menu, but will not open.
I would be extremely grateful for any help anyone can provide.
Thank you.
