I can not activiate new devices because I have hit the 6 device limit. I no longer have 3 of the devices so I can not do it on the device. When I have gone to my account, there is no list or any way to see what devices I have listed. All I know is that I have hit my limit and can not make my new ereader work. Is there anyway to do this without creating a new account with a different e-mail address?
