Just downloaded the newest update for the Calibre. This is what it said when I plugged in the Sony Reader. This has never happened before. I reset it, but won't let me get past Enjoy the new revolution in reading on the welcome screen. It should have been past that after I unplugged it, but it won't do it this time.

Errno 22] Invalid argument
