My guess is the OP bought a blacklisted Kindle. Blacklisted means Amazon knows it was stolen or lost and they disabled its ability to be registered. Not capable of being registered means no dictionaries from the cloud.

Fixed probably means that allowingtoo, who we know bought a blacklisted PW1 on eBay from his admission on another thread, probably deDRMed a dictionary and sent it to the OP. That is my guess.
