And, you didn’t say: did you try to reset the player? Try holding the power button down (Clip+) or power slider up (original Clip) for 30 seconds or more (up to a minute or more).
Also, it’s been reported that sometimes the battery needs to fully run down before the player will start up again. Sometimes just leaving the player alone for a few days, letting the power run out (even if the player is off), can accomplish this.
