need help moving files to another computer

[KILLAHDANKS]

I have 2 computers, I download in our living room on our laptop. I have a shortcut on my computer in my room where I can access the laptops local C: so I can take all the music store it on there and move it to our I Pods. Now so far this has worked great with Win MX but Win MX does not work as well as I would like. When I go to copy these files it tells me, ERROR: Make sure files are not a complete cd or make sure files are not in use. I have tried taking them 1 at a time samething happens. I have WIN AMP and Limewire on the laptop, and I have I Tunes and WIN AMP on the PC in the other room. It is all run through a Linxus router, I can turn on I Tunes on my computer and see all of the music but cannot get it on my Computer I did this so we do not have to flood the laptop with music but now here it sits. If anyone can help I would appreciate this more than you could ever know. Normally I would not bug you but the guy who built my computers is on vacation in Hawwaii and thats far away. All I am trying to do is copy the music from one C: drive to another and its not letting me, whats up with that?
