Downgrade to calibre 3.44 remove the .json files, restore the .py files. 3.44 will correctly migrate the preferences files. Then upgrade to 3.45.2 and you should be fine.

OK, it looks like I upgraded from 3.40 to 3.45.2.
I'm not quite clear on the instructions. You said to delete the .json files. All of them, or just the smtp.py.json file? Unfortunately, I'm having difficulty accessing the files from my backup. Still working on that.
Apparently to downgrade to 3.44, I need to completely uninstall Calibre. Won't I lose all the settings and configurations I already have?
Sorry, I'm really not clear on the sequence of steps, and I definitely don't want to lose what I have. Most of Calibre is still working, so maybe it's easier to just reset my preferences and re-enter the email addresses?
You said this problem will be fixed in the next release. If I just wait for 3.46, will my email addresses and plug-ins magically re-appear?
Thanks for all your help.
