Loading song Issue with Macbook Pro

I placed Cross DJ on my friend's Macbook Pro. His songs play in iTunes and are recognized by the Cross software when you open it.
But when I try to load a song to a deck,
the software says "song can't be found".
I checked the pathway on my Macbook Pro and I used the same one for his. Mine works, his doesn't.
Here's the pathway.
Users/username/Music/iTunes/iTunes Music Library.xml
Can anyone help me resolve this issue
