This whole thing is getting ridiculous. Adobe digital editions does not work with books in this format on the Elonex ebook. As lots of people have said, you just get the message "No valid lisense"-their spelling not mine. So You do't bother ringing Waterstones- you can see from this blog that they have no idea.So you ring elonex who quicly let you know that the only option is to contactAdobe.So after lots of emails they ring you and give very confusing advi ce that they don't know if this ebook works with digital editions but it may not be working because the permissions haven't been downloaded, even though I am able to read my books on my laptop with my Adobe password. So now I wish I'd never bought this piece of junk that I can only use to view non-copyrighted books.I think I will go back to real paper books because life is just too short .Any body want to buy my book for about £100?
