[iPod Nano 2G] Cannot play music

[G4Oblivion]

*EDIT*
I uninstalled the bootloader then reinstalled. Got the newest version of Rockbox and the problems gone.
*EDIT*

Hello, I'm using a iPod Nano 2G Firmware 1.1.3

When I try to play a mp3 files under "Database" I get this error:

Undefined instruction
at E59F30D4

I'm using Rockbox version r25020
This started happening somewhere between r25003 - r25020

My iPod plays video fine and the sound works on video.

If you need anymore information just ask.
