Hi theelziebub
Why not try the following:-
Buy a flash drive (pen drive) these now come in a 4GB size for
about �18. See
http://www.ebuyer.com.
Fire up both PCs and copy the music folders you have created on old PC to new one by creating/naming them. Plug in flash drive to old PC and copy to it all it will take from old music folders. Click on your flash drive icon left of PC system clock and disconnect drive.
Now plug flash drive into new PC and copy music to the same folder names on new PC. Repeat this until all your music is duplicated on new PC.
Reinstall the software that came with your ipod onto new PC. This should be safe and quick as you still have old PC as a back up until you are happy with operation.
