Hey, I had the same problem, it looks like I got the same sigmatel mp4 player. I put the cd that came with it in, ran the setup and it completely died. I noticed on my driver cd there were 2 directorys with setup programs.
- 1.5 5Key*********
- 1.8 5Key*********
It installed the 1.8 version, I uninstalled that software and ran the 1.5 version and the player came back to life (in chinese, I managed to navigate to the settings and change it to english) now it's alive again.

Hope that can save your player.
