A mp3 player (Zen Nano, if that matters) attached to a computer. Till now worked just fine.
Windows upon attaching didn't give any message (no baloons, no nothing). I thought the thing has died. Then I downloaded NirSoft's USBDeview, and it showed that it's still there with a drive letter F:
The player's normally accessible through command prompt. I can do everything with it I normally do (copy files, delete files ...). If I start explorer from the command prompt (via "explorer .") it won't start. Nothing happens. If I start explorer via start menu, it doesn't show the drive.
Any ideas ? All suggestions appreciated.
