E_ACT_NOT_READY keeps on popping up when I download a book I purchased. I can't seem to open a book on my imac computer. I have the latest edition installed, which I installed just for this book. I can't seem to find a spot to "login" into my account. I've already asked for help somewhere else and no one can seem to help. I was some how able to install the app and open the book on my ipad as it asked for my adobe login. I have had no luck on my computer though, which is the only way to print from the book.
