forgive me if this is discussed elsewhere, but i'm having a problem where, 2 days after using the unit successfully in my new apt, the unit now shows an N at the bottom left corner of the screen. i can navigate through the tree structure of the 2 usb thumb drives i have attached, but nothing happens when i try to play the files. multiple restarts show the unit in a "cleaning up" operation for a good long time.
any ideas? thanks in advance....
