Share Books By Email Suddenly Not Working

I am using latest update. 9.2.1 but this started yesterday BEFORE I did the update. Suddenly I can't share by email any more. I tried shutting off my McAfee that didn't make any difference and it's in McAfee as an exception anyway. This is the error I get when I send a test email:

Traceback (most recent call last):

I am using the same email I have always used. I am sending to the same email I have always sent to. Any idea what's going on?

Thanks
