At some time I get rid of all my /MUSIC dir (iAudio X5) and upload new music there.
When I turn RockBox again then, it says "Nothing to resume", this is OK. And then if I trye to play any song, is hangs immediately after "Play" button.
Before I tried to manage this reinstalling RockBox, but this is silly and now I press "reset settings" in RB menu, then re-set all the parameters I need, then I start playback. And it starts.
So: After new music upload settings reset is needed. Is this bug?
