Gaming devices may be registered via MAC address at the game registration page here.  Keep in mind to use the MAC address for the correct adapter on the device.  Ex. wireless Ethernet cards have a different MAC address than a wired Ethernet card. For help with finding your MAC address please view the page here.  You may need to refer to your device manual for help finding the MAC address. 

If you get the error "The given address does not appear to be valid for a Gaming Device", please submit a ticket with your full MAC address and device type.
