Sansa Express not recognized by XP

So I am assuming that if I understood what you were telling me to do I could fix this problem…I have a laptop and desktop configured exactly the same.  I WANT the sansa to use my Desktop but i too get the insert disk msg.  I have upgraded to WMP11 …I didn’t understand " would check Disk Management and see if it shows up there"  Can anyone help please.  I do like the device, but…:wink:
