the "asus-pc" link at the bottom of the aplication should point to your windows media player shared music, one of the issues i had was the third party firewall in the windows 7 64bit pc was blocking traffic(not all firewalls are the same, so i cannot comment on how you can check this), i set the firewall to learn mode and it then worked(learn mode basically automatically creates rules in the firewall for any process trying to use the network).
