Thanks, but this was the site that worked, but screwed up the fonts and layout.
Thanks, but this was one of the ones that took forever, then finally reported “Sorry, we hit an issue when converting your file.”
@Edward_The_Head, thanks for the suggestion, but the files are displaying the same on another computer.
Trying online services was just an act of curiosity, but wouldn’t have been practical even if any had worked, since I have about 220 files to process, and uploading and waiting for them all to be processed, would have been a nightmare. To say nothing of the fact that I would have had to pay for a process that should work quickly and easily on my own computer.
My next step will be to see if Adobe can be any help. But given my history with them, I’m not hopeful.
Thanks again for all the ideas. If anyone has anything else, please let me know.
