moving i tune from one computer to another

"pc makes everything oh, so much more difficult"

Nope... that award went out to Bill Gates' "oh so marvelous and intuitive, crash resistant, and security ladden" Operating Systems the world has come to admire and covet so overwhelmingly. ;-)

thanks for all the advice, i set up itune on my new laptop, but i can't seem to get it to work with airport express, when I try the hagman usb-coaxial converter , it works fine , but when i try to send wireless, it am getting an error message, is there a problem with window vista and apple Airport?

check for a Vista driver update for the Airport... if all else is configured correctly.

Perhaps something in the router needs to be addressed as well.... like selecting the right freq. G; B; A; etc.
