Thanks for such a quick response. You may well ask why, if I can download the same titles from Gutenberg, I wish to bother with Adelaide. The answer is that I sometimes wish to download separate short stories from an entire book, or (as in this case) separate chapters from a large text. (Of course, I can -- and have -- downloaded entire Gutenberg books in the txt format, copied to my word processor, edited out the unwanted 90% of the material(!), then save back as an abridged txt file and converted it to html then to Mobipocket, as described in my initial posting. Very convoluted, indeed!
Anyway, my failed experience with the Adelaide titles seems to ALWAYS be the case, so I suggest that you just download from their site any title you want and see what the problem is and hopefully rectify it. Again, many thanks, and regards, Jim
