I thought mine was too, since I'd had mine for more than a year. But when they did the last software update, my device was no longer authorized. An online chat with Sony resulted in them directing me to Adobe Digital Editions and making an Adobe account and authorizing my eReader. This is a new change, and applies to all previously purchased content as well as new purchases.
