It is relevant because it demonstrates you did not know what was happening and didn't actually make much of an effort to work out what was happening. The only update that would have made things work again was an update to calibre that include the support for the latest Kobo firmware. And even that was easily handled with older calibre versions.

regarding the database, my experience says you are wrong or don't understand why it resolved the issue. the log showed me the folder path and it was not hidden or a system file. it didn't exist. once i created the folder in explorer manually and reconnected the device the functions starting working with no errors and files appeared in that folder.

No, I do not understand how if fixed the problem. But, you do not understand that I am the person who maintains the KoboTouch driver in calibre, created the Kobo Utilities plugin and am at least a little involved in all the other Kobo related plugins that exist. I know how this works. What you said is completely and utterly absurd. If that directory did not exist, the device would have detected it, rebooted and then prompted you to do a setup. And I do know this from experience. I have done lots of experiments with what happens if certain files are missing or replaced.

and why is it the first problem i should have started with? if, as you say, sending the book doesn't require kobo utilities, then i was using a completely normal and supported method of everything i was doing. load properly named fonts, drag books onto device directly. and it was working, so i believe these were separate issues.

Because that was what the actual problem was. Or at least a symptom of what the actual problem was. Something more was going on than the device than just not showing a book in the list. We also assumed you were using calibre to put the book on the device. That is why I asked if the book was actually on the device. I wanted to know if the send-to-device was failing in some way. If we knew that calibre was having problems communicating with the device, we would have been asking different questions. Just as if we had known you were manually copying books to the device, the questions would have been different.
