Try running the firmware flasher issued from Sony. It's definitely still available and you would have needed it to follow these steps anyway.
The Sony Updater is an archive: decompress it into a directory and edit the file: PRSVersion.dat:
That file contains a string 110018040 - change it to 110018041
The Sony Updater should then run and update your Reader.
