Thanks for such a quick response. I do tend to use the discover books by keyword quite often. Also, I saw on one of your earlier posts that I should l have put the log in a "spoiler tag". If you could tell me how to do this, it would be helpful.
Also one other thing, although I think it is Calibre itself that is giving me this problem:
Signing in to HOOPLADIGITAL.COM: Retrying
www.hoopladigital.com on exception URLError ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)).
The info I have found so far refers to python 2.7.9 which is what Calibre has moved to.
Luckily it only affects Hoopla. As always, I am grateful for all the hard work you put into this program.
