I have a ma450ll ipod which when I plug into the pc it acknoledges a plug in but says it does not reconise what it is. Also do I have to have Itunes download to make it work as I have tried to down load it now about 20 times. Goes through the process but at the end just tell me that somthing went wrong with the down load. Is there any way to get my pc to eccept the I pod. I am using a different pc from the original pc that was used with my ipod before. thelilypondhouse@gmail.com
