Can't copy songs from computer on same network

Hi
I have a Macmini and my wife a windows laptop. We have cable DSL so are on a home network thru a router.
When she downloads songs from her laptop from Limewire they show in my ITunes while she is logged on but ITunes won't let me copy them or upload them to my IPod.
Can anyone advise if this is possible?
Thanks
Guy

iTunes will not let you directly copy... You would have to set up the folder on her computer to be a shared folder on the network and then copy the songs from that folder and add them directly to YOUR iTunes library... Let me know if you need any more help if you cannot do this on your own.
