I've posted a couple times in the past day about Kindlean not working with the new 5.1.0 patch.
On the Kindlean site they say they are working on the problem. If your like me though most of the books you're interested in are series and being unable to sort them into collections is rather annoying.
Until Kindlean patches, its possible to
Jailbreak your 5.1.0 Kindle Touch and use the program.
