Hello, I have just recently bought an ebook from Kobo. It is a manga/graphic novel just to let you know. I downloaded the acsm file from Kobo and I successfully used that file to download the epub file with Adobe Digital Editions. I have authorized my copy of Adobe Digital Editions with my Adobe ID. The epub file has the correct book title, author name, publisher information, and number of pages. The problem is that all of the pages are either completely blank or have a line across the top of the page showing about 10 pixels worth of the page. Below is a picture of what I am describing. I have tried re-downloading the acsm file and I have tried re-downloading the epub file multiple times with the same result. Does anyone know why this is happening and/or how to fix it?
I am having the same problem. Were you ever able to resolve it?
According to my research into this, the reason the book does not display correctly is because it is protected by a special Kobo DRM that is not compatible with Adobe Digital Editions commonly referred to as Kepub. The file type of my book on the Kobo website says "EPUB 3 (Adobe DRM)", so watch out for books in that format.
From what I can tell, the only way around this is to remove the DRM from the epub file. I would like to add that removing the DRM from anything is illegal, and I do not condone this action nor am I recommending it. I am simply stating the results of my research.
