Hi,

I am unable to load books via Calibre or Windows Explorer.
I'm having a problem loading new books since updating my Kobo Glo firmware to 4.3.xxxx I found today that 4.3.8945 had been released and I was hoping this update would resolve my issue but it hasn't.
I have updated Calibre to 2.81.
Kobo Glo FW 4.3.8945
Steps I complete:
- In Calibre I select the book, right click and select send to device main memory (my standard practice).
- The job loads in Calibre - I check the Jobs log and it completed 100%.
- A green tick then appears in the On Device column in Calibre.
- I then check via the Device - Show Books in Main Memory - the book appears in there.
- I eject the device, the kobo processing content progress bar ticks along, and completes
- my kobo loads and opens as expected
- I check my library, sorting by unread and recent - no new books since before 4.3.xxxx installed, I then perform a search for the book I loaded, the search returns no results.
The really weird thing is, the book is loaded onto the Kobo - I check via windows explorer - the epub is in the folder as expected.
If I load the book without using calibre, just add the epub to the (already existing) authors folder on the kobo main memory drive, upon restart, the kobo processing content progress bar ticks along, and completes but the book is still nowhere to be found via the device (I can see it using windows explorer).
I have checked Calibre and the Attempt to Support Newer Firmware is ticked / I've had it both ticked and unticked.
I have also tried with other epubs - the same Calibre process above and again the epub file appears in the folder list when viewed in windows explorer but cannot be found via the device 
Does anyone else have this issue?
Does anyone know what else I can try before I go for the factory reset?

thanks in advance.
