I have been using my Sony eReader via Calibre for nine months. I've never had a problem until today. This afternoon during the middle of reading, the screen went white, and came up with the circling arrows that usually indicate something is loading. I plugged the reader in to charge, thinking that the battery had gone down, and tried to open the book I'd previously been reading wouldn't load. Up came the message, "Protected by Digital Rights Management."
I decided to erase every book from the reader and reload via Calibre. Same issue. Now, in Device Information, it says that the device is not yet authorized for DRM Content, yet I had been reading a DRM protected book up until the strange crash.
How do I authorise it now? All help would be greatly appreciated!
