Hi, I bought a book from google play and read it on play books. Then I deleted it and can't seem to get it back unless I go to the store. Most of my books are old epubs, so this situation hasn't cropped up before. When I go to the store and search for the book, it gives me the option to read it, which opens it in play books. BUT when I close the book *poof* it's gone and I have to go back to the store. ??? Anyone else had this problem?
