about this topic, I have the same problem only on mk3, I saw on the screen LOADING SOFTWARE and then black screnn, and red light on CD went off. I was able to get the CD to eject, this same situation as you.

I have some questions:

1) What media type CD did you use when all go wrong? Comp-USA media ?
2) What media type CD did you use when you success ? SONY CD-R ?
3) What version software did you use to restore navigation? Can you show the place where I can download this version ? What speed and what program to burn CD did you use ? Did you make verification ?

Thanks for help
