Your player software is crashing. Sometimes this is due to a corrupted tune.

I think the usual "fix" is to wipe the flash savearea, by manually using Control^C to kill the player, and then restarting it with the flag (??) to tell it to reset its saved settings.

But for your case, I think I'd like you to try a Hijack fix for it.. I'll release Hijack kernel v420 shortly (in a few minutes, at the link above). This version of Hijack automatically attempts to clear only the current playlist setting when the player crashes, rather than all of the player's settings. Let me know if it solves the problem or not (by posting here).

Thanks
