I have a Sony e-reader, model number PRS-600, serial number 14840337 1473535. I have downloaded an e-pub book from my library to my desktop (Windows 8). I installed Adobe Digital Editions on my computer. When I open ADE and drag the e-pub book from my desk top to the e-reader symbol on the ADE screen I get the following message:
Unable to Download
Error getting license. License server Communications Problem
E_AUTH_BAD_DEVICE_KEY_OR_PKCS12
I don’t know what to do.
