Windows Vista problems

I have the new windows vista,and I cannot seem to be able to play music on my computer. I plug it into the usb port while it is turned on, and the options menu comes up, and it will not allow my to play my mp3.
I go to the hard drive and click on the removable hard drive files, and none of my songs appear. all I see is my recording file and WMPinfo. none of my songs. but they still appear on my player after uplugging it from the computer.

does anyone know how to fix the solution?
