"Bad track" error

My Sansa e140 just died, so I bought new Sansa c250. I copied all tracks from old unit to a new one, after setting it to MSC mode. Now, when I turn the unit on and select play “All” music, i get “bad Track” error and the unit freezes. Every time this happens, I have to remove the battery to restart the unit every time. The starnge thing is all tracks played fine on old unit, and since no title is displayed, I don’t know what track causes the error.

Did anyone else had this problem? How did you solve it?

try formating your player and retransfer your mp3s. there  might be a corruption of the files in the player.
