I've only been really using Calibre for a few months. I've been able to bulk-download metadata for most of my books. That is, up until about a week ago. Now can't download any data for any book. I've been tinkering with my settings, so I may well have "broken" my setup. I went to my Configure Metadata download settings and did a "Restore Defaults." I don't have any Plugboards setup. I did set up a Custom Column, but I was able to do one or two bulk downloads since then. So I don't think that's the problem. Not sure though...

Any ideas what setting I might check?

EDIT: Hmm... I just tried to "re" download for a couple of books that already had their data retrieved. Metadata for those did seem to download and install. Then I tried it again for a few of my more-recently added books and no luck.. Here is the error info:
