I just purchased a 4gb nano, but i can't install the software on my ibook G3 dual USB. I realize it doesn't have a USB 2.0 port; could the software be recognizing this an thus not allowing me to install? I get to the point in the install program that asks which drive I want it on and shows how much space it will take up. It indicates that "0 bytes" are required for the install and then the next step won't let me install any of the packages. Any help here?
