not sure about this but when you look at the main menu page does it show "Digital Editions".-I thought I had installed the firmware and this wasn't showing.When I re-installed it it was showing so double check the installation on the ebook reader- try deleting it and then saving the two files to the memory card again.If it has installed properly it will return you to the main menu after installation.Hope this is helpful if you haven't already tried it.
