Ok im trying to set up a game with my friend and i (before you guys rip on me we arnt that fermiler with setting up lan games)

 But 1st I tryed to play on Iron Clad or whatever its called and it keepes saying i dont have the right version of iron clad. i downloaded and installed the update for the game from the update tab on the menu, and it still says the same thing. so if you could help me find out what is wrong with that that would be awsome

and 2nd how would i set up a LAN game if i wanted to?
