It sounds as if you have two network cards on your laptop or you have added or changed a network card. NV2 was registered when one of the network cards was the main network card and now the other network card is the main card used on your system. Laptop machines come with wired and wireless network cards.
You will have to call Customer Support at 905-946-9460 to register the other network card and keep the original registration in case your system reverts back to the original network card.
A solution to this problem should be ready by the next update to NV2 (2.08).

Martin
