Rhythmbox 0.11.5 files, playing message and iPod

Hello,

I have this software in version 11 and receive a sleep warning message everytime i try to begin playing any musis. Is there any way to solve it please?

In addition, my library location is set properly but none of the files are there while they still play. The ls -lisa command returns nothing. How come? Where are they because the locate command works?

Finally, how can I copy the music files to my iPod (it shows up fine in the computer).

Thanks,

André Luiz
