Verified that I was running 1.1 and cleared Data. Just so you know but that does NOT remove the books as I previously found out. I went in using ES file explorer and deleted books manually.
Restarted the app, reconnected with Calibre, and pushed 4 books. The very FIRST book that was sent brought up the error. The tablet still shows:
Syncing with calibre
Receiving books from calibre
Receiving "Book Name Here..."
I get the same error in calibre as per usual.
The tablet is a 16gb device with 14gb free. I have also tried changing the storage to the external sd card which is also a 16gb but a fat32 formatted device but this does not affect anything.
Anything else to check?
