I'm running UnleashX and I have the latetest version. I installed a new skin and when I rebooted the Xbox the skin would freeze after 6 seconds, I managed to make the Xbox return to the default skin, but after 6 seconds the Xbox freezes still. I've tried holding back and it did return to the original skin but it still freezes after 6 seconds.

I have figured out that enabling music to be played freezes my Xbox, I don't think it's the skin.
