Clip+ won't open using Windows 7

Try setting the player to MSC mode, then try the following. Connect the notebook to the wall charger before plugging in the Clip+. Disconnecting all other usb peripherals before connecting the Clip+. What happens after you connect the Clip+? Have you tried opening Windows Explorer(right click on start, click on explore) after you connected the player to see if the pc has it listed there? It might be that the pc is recognizing the Clip+, but not taking any action, and not opening a pop up window.
