I converted the EPUB books to MOBI then I sent it via gmail. It was sent successfully but when I click on the book, it flashes 'queued' then it doesn't open. How can I fix this?

Also, I get an error when I transfer via USB.

calibre, version 3.39.1
ERROR: Error: Error communicating with device

[Error 3] The system cannot find the path specified: 'D:\\documents\\Wright, Tristina'

Traceback (most recent call last):

Help would be appreciated! Cheers!
