copying to device takes too long

[jpbn]

on mac 10.9.5 digital editions 4.0.3.11. 

copying to Kobo Aura

(your error messages cannot be copied, that is not friendly, now I must copy that by hand.)

CE_Failed_TO_WRITE_DEST_FILE failed to write destination file.

what to do to copy my copy of the book to my ereader (Kobo aura)?

[jpbn]

when i retry the dig edit tells me the book already exists on the device.

is not that very weird?

do you really test your software before publishing?
