OK! Problem seems to have been that I bought a new iMac, and reinstalling DownloadHelper (several times) which caused the problem (the instructions were, unbeknownst to me, in my Spam folder). Also, in Settings, had to re-set the Behavior of Download Processor to Companion Application; It reverted to "ask," but didn't ask ... and downloaded as audio only. Changing it to Companion App. (only) fixed it. THANK YOU for the BEST downloader available and your great help, mig !!
