download problems
 

I downloaded a song from limewire and am trying to put it on my mp3 player. I have the mp3 player plugged in the same usb port as I use for my digital camera. Is this the problem? Do I need to plug it in a different usb port?

No, any USB Port should work.
Does your computer recognize the MP3 Player as an additional HDD?? If it does then go to your shared/saved folder Outside of Limewire and then you should be able to either drag and drop or you can transfer them from the shared folder.
