It is an error message on the screen when I click on "Public Library" The reason I want to do this is because I want to borrow books from my library wirelessly. I don't have a windows desktop (which is why I am at my husband's office, to download and upgrade the firmware).
Anyway, I was able to register at the sony store and then at ade after a bit of user error :O and finding out what to do. You all have been very helpful. I now am able to enter my library credentials and start borrowing books.
