Query: WILL CRASH YOUR COMPUTER!

This is very frustrating. I bought this for my 11 yr. old. Her B-day was yesterday. She was excited about getting an MP3 Player and since yesterday afternoon, until this morning I have been trying to configure the stupid thing.I have windows XP OS so according to the "clear instructions" you don't even need the installation disk (but the firmware cannot be upgraded, no matter what you do).Twice a FATAL Error was caused on my computer. The website (when you can find it) does not even list this item.The buttons are fine, but the menu is very complicated and hard to see. The backlite creates more shadows than iluminates the menu.Save your money and don't put up with this headache! Am returning the item and shopping around for something else.Sorry for the long post, but this thing is useless, and potentially, it could damage a very expensive computer system.
