how come when i turn on my a608 it says "function limited". i already tried formatting it today, and it still had this problem... basically, when i hold the FUNC key, and i goto the "Intelligent Shuffle - Music Library - FM" menu, "Intelligent Shuffle" is greyed out, ie. i cant select it. has this happened to anyone else? i reckon its cos of the songs i have in the machine (right now i have 313..), before when i formatted it, and i put one song in, the Intelligent Shuffle worked... anyone know why?? (and i do have unicode characters in my song titles)
