I have previously bought and downloaded a book successfully from Waterstones. Also downloaded a free book from another site. However the two I have purchased recently from Waterstones downloaded to Adobe Digital Editions ok and then transferred to my Elonex ereader ok. When I tried to read them and clicked on the title to open them I had a message window that said "No valid lisence for the book." I have contacted Waterstones and also Elonex support. Elonex told me to contact Adobe, which I did, but after trying to explain and then finally being put through to technical support the line went dead!!! Just wondered if anyone knows what is wrong and if they can offer any help.
I'm having the same trouble over 4 years later. I can't find any useful info so I thought I'd reply to show this is still a problem as your post has had 277 views.
