OK, so it's been a while since I dedicated 50 hours a week to this problem, so I don't remember everything (I should have written it all down, but was sure I'd never forget - LOL). I think if you go back to my old posts, there is a solution, Bluey. If you have files that are called .DML in your profile, it won't recognize them. They have to be called .dml. You can do a batch rename on them. I seem to recall that what I did was recover the files with software from download.com, save the recovered files to a folder on a separate computer or internal hard drive, then I renamed them to .dml, then I deleted everything from one of the folders in my profile on the Passport (usually named a, b, c, d, and so on), then copy and pasted the recovered, renamed .dml files into that profile folder (just dragging and dropping via Windows Explorer), and then ran the decrypting software from DMailer, and it recognized the files and decrypted them. Unfortunately, I figured all that out after a 2am mistake where I overwrote most of the files I need to recover, so I got like 5 out of 100s of photos back. But try that - it should work for you. Read all my old posts. I don't give you every detail because I'm a broke Ph.D. student who was hoping to simultaneously help people and put a little cash in my pocket to make up for all the time I spent figuring this out, but most of the info is there and I can try to fill in blanks now if need be. Again, it's been a while and I'm super busy now that school is in session.
Everyone -- KEEP IN MIND, the DMailer software is NOT recovery software. It is decryption software. What you need to do (i.e., the big picture) is RECOVER your encrypted files from the Passport using third party software that you get for free from the web THEN decrypt those recovered encrypted files with DMailer's software. Somewhere in there you may have to rename the recovered encrypted files so DMailer's software recognizes them.
DMailer is not particularly helpful. In fact, in the long process of working all of this out, they asked me (1) not to email them anymore or they would block me and then (2) how I did it once I told them I got it to work. I don't think I told them.
