Hi everybody, I,m from Spain and it,s my first post in this forum... and I have a problem. I bought the nw-e507 in Japan, and after installing SonicStage and download music to the player it was all OK for two days. Then something strange happened. When I touch any button (Play, volume, etc), the song goes back (and Shuttle is not pressed). The Disp and Search buttons don't do anything. Reseting the player and upgrading firmware don't solve the problem, and of course I'm very accurate whit the player (no shock, no water, etc). Can someone help me? Because this player only worked fine 2 days. Now I only can see how the songs list go back without touching any button. PD: I try enter the test mode, but in HOLD state, pressing Play+Reset only make a simple reset ("Data access" is showen) Thanks
