I bought my Elonex 2 weeks ago, and allowing for known bugs was very happy with it. i have also managed to install the firmware update from Elonex which installed OK (apparently) and seems to have fixed my free book problems as well as allowing UK date and time formats to be entered in settings. However, when I try to open the book bought from waterstones, (visible and readable on my PC screen0 I get the message 'No valid license for this book'. have raised the issue with Waterstones on line but so far no response. i see that several other people on the waterstones site are also having the same problem. Not sure whether its formware or Waterstones site or Adobe - but very frustrating.
