98% of the way there ... but I have 8 clues needing 2 letters to be moved. I don't think at this late stage i'm giving too much away by listing them: 1, 7, 9, 17, 21, 24, 30, 33. Which one am I including incorrectly? And while I'm at it, the message in Ring 5 is 5,8,6,3,4,10 I assume, but the 3,4 means nothing to me. Perhaps my two errors are lined.
