Hello, I just got a Clara HD and used Calibre to move my .epubs to it so they beecome .kepubs.epub. I couldn't transfer one book because it maybe was too large. It is Summa Theologica by St. Thomas Aquinas, size is 9.8mb. This is the error message I received.

calibre, version 5.22.1
ERROR: Error: Error communicating with device

Would anyone happen to know what went wrong and if I could transfer this book?
