Ok thanks.

I use my md player everyday, does anyone know how to fix this? Many thanks!!!

A few months ago I succesfully hacked my Sony MZ-N505 following the instructions I found at minidisc.org. Today I tried to restore the unit's original settings, but I must have done something wrong because when I try to play a disc it says "NV ERR" on the display. PLEASE HELP, my Minidisc player is unusable right now. Many thanks in advance.
