Due to Kunos Simulazioni deciding to focus on development of Assetto Corsa, Kunos will end support for netKar Pro on 1 December 2015, as well as shutting down its multiplayer servers.

More notably, they are no longer checking activations of the game, so you can now share your purchased keys with your friends to activate the full-featured game as many times as you like.
