Trouble Managing Collections on my Kindle Keyboard with Calibre
I'm getting the following error when I try to push collections from Calibre to my Kindle Keyboard:
calibre, version 0.8.70
Kindle Collections: <P>Collections saved to the Kindle.<P>
55 collections, 375 books found on the Kindle.<P><P><B>Eject and <U>Restart</U> the Kindle to load your changes.<B><P><INDENT>To Restart: press the Home key, then press Menu, select Settings, then press Menu again and select Restart.</INDENT><P><P>1 warning message.
=== Kindle Collections Report
The collections on the Kindle have been edited since the last time Create Collections was run. If any Calibre-managed collections were edited the changes made previously (listed below) were ignored. Any collections listed in the Never Delete field in Customize are not checked for changes.
Collection "! Unread Books" has a new item: Book with no file - #B003V4B4PM^EBOK
Collection "! Unread Books" has a new item: Book with no file - #B007AIT20E^EBOK
Collection "! Unread Books" has a new item: Book with no file - #B003V4B4GQ^EBOK
Collection "Old Man's War" has a new item: Book with no file - #B003V4B4PM^EBOK
Any thoughts as to what's going wrong?
