IP Configurator problem

[Progettografico]

Hi, I'm trying to set up a LaCie 2big Network drive with IP Configurator.
The problem shows at the start with the message:
"Congratulations! Your Ethernet Disk has been set up successfully! Select the Ethernet Disk and click on the Connect button to access"
But the list is empty! I cannot see my disk, why? :?
