Help!! Computer freezes, can't transfer files.

Hello, I just bought a 4 gb fuse.  I plug it into my computer and it comes up that it is recolgnized, I can click to open folder but if I click to open the internal memory to add songs the folder freezes.  If I tell it to open into rhapsody and try to click and drag from my library, like it says, it freezes.  If I open windows media 11 and click on sync it freezes.  The fuze connects to the computer, system says it’s working properly, I updated the firmware but I’m not able to put anything onto it!  Any suggestions?  I meet requirements, I’m running WinXP SP3, Win Media 11, and am hooked in through the usb.  I don’t know what I’m doing wrong.  :cry:

This problem was solved.  It was the USB port I was trying to use.  Once switched to another port it worked fine.
