I have Kobo on my PC and have downloaded books. I synced them to my Galaxy Tab and was happily reading them from there until today! I downloaded an update on my tab and now the books are there but it says they "aren't available yet", whatever that means. I have hooked my tab to the pc and used the sync on Kobo but it doesn't change the availability of any of the books. I am halfway through a book and am so frustrated. Don't want to sit at my computer reading, want to take my tab with me and read when I can. What went wrong after the download? and can anybody help?
