Yup, I just randomly got it too. haven't read much for kobo's books. But today i randomly decided to read one that came preloaded on my Wifi. I tried opening the book and my wifi told me "this book cannot be opened, please sync with kobo and try again".
pretty much imposssible while sitting on the train. I moved on to a sideloaded epub instead. issues with kobobooks drm and such make me very skeptical of ever buying from them
