PSP freezes when I press the music button on NitePr!!

[Lonestar]

Okay here is what I did.

1. Downloaded NitePr (Stable) and installed onto my PSP (Custom Firmware 3.71 M33-2)

2. Activate codes I like the sound of such as Infinite CE by pressing the square button (because I wanted them on all the time)

3. Exited and pressed the music button and when I tried to load something (like the customization screen) it would freeze and crash after 30 seconds

4. Reset my PSP and steps 1-2 and pressed the music button while in a campaign mission. But to no avail it didn't work and would also freeze and crash

Whats wrong? :blink:

P.S. My PSP is a slim (old slim not new one)
