The key to this player is that it has many little (annoying?) nuances:
1. The firmware is on the CD (Jukebox Restore) and will only properly work on computers with Win '98SE and anything later. Always turn the player on first and when it has started up fully then you can plug in the USB connector to the top of the player. I got the Runtime error when I was using a comp with only Win'98 installed.
2. To download songs onto the player from Windows Media, insert your CD and you need to Rip the songs onto your computers hard drive (in Windows Media 10 there is a tab at the top for this).
IMPORTANT: MAKE SURE THAT (THROUGH THE OPTIONS MENU HERE) TAHT YOU ARE CONVERTING (RIPPING) THE CD AS MP3'S.
Once a CD has been 'ripped' you can 'Sync' (tab at the top) these with the 'Jukebox' (your player). When you turn your player on, all of these songs will appear in the EXPLORER option on the player's menu. **I would love to know if anyone knows a way to put these on the player so that they appear in the 'Artists', 'Genre' and 'Year' etc, sections too?**
3. If the player appears 'stuck, frozen etc. Press the buttons 'Play', 'Menu' and 'Select' simultaneously and he player will re-set - this has so ar cured any big problems I have come across (especially with trying to Install Firmware etc.)
4. You can view all of the info on the player by going to 'My Computer' and looking in 'Jukebox' treating just like a regular hard disk (you can even store other unrelated files for transfer on it if you wish).
Hope this make sense
