Regarding my previous message below, "No valid license for this book" I now have too many activations!!! Also when I try to transfer any purchased books from ADE to my Elonex reader I get a message saying, "No permission to copy document here." I seem to be getting more and more problems! Any help at all would be greatly apprectiated. I have spent many hours today on the phone to Waterstones (where i bought the ebooks), Elonex and Adobe to no avail.
