Just did the update with CWR and the pre-rooted 1.1.0 and everything seems to be working fine, except that my library is now empty. If I go into the shop, to a book i've already purchased, it does not give the option to download it again, but if I click the purchase button it pops up an error saying I already own this book. I can download the books into My Files on the nook via usb, and then they will show up, although the book covers are blank.
