Thanks for posting your fix Martin - although it didn't work for me (I don't have that setting on page 4 of my 511EB), it gave me the incentive to keep trying. I'd like to tell everyone with the same problem what worked for me but I'm not entirely sure. I deauthorised my Digital Editions software (CTRL+SHIFT+D) and then reauthorised it. This meant when I reconnected the e-reader, it asked me to authorise it again. I'm not sure this was the problem though because the first time I did this it didn't work. HOWEVER I tried again and this time after I reauthorised the reader, I chose Safely Remove Device from the task bar instead of right-clicking the reader in Explorer and selecting Eject which is what I did before. Hope this helps!
