strange problem ! a USB connection i assume.
Did you install software and drivers that came with the mp3 player .
have you check to make sure there is nothing in the end of the usb cable from the player,or its not bent , most computers have 2 or more usb connections have you tried both .
Next if you right click on mycomputer go to properties ,hardware/device manager ,t the end of the list is the USB device any yellow or red ! marks their ,if no ,you could try hitting the + next to it and removing all in there and rebooting computer and let windows reinstall the usb device drivers .then try plugging the player in again and see what happens ,if it detects it you Will be asked for the usb drivers for the player .

THanks for the reply. I ended up getting a bright idea and tried this... Sandisk makes a card writer/reader and for some reason this works. So what i did was use my 512mb sd card and loaded songs onto that, which i then put into my player. Works great like this. Not sure why the player wont do this. Thanks anyway, T. J.

How do I turn on the player when it was left on, overnite so after that I can't get the player to turn on any more? Thanks this was mknoise.
