Hello, I'm new to the game / forum, and I want to play with my brother, but 2 original games do not connect the Internet, so we decided to play via LAN "local area network," our games are not found, it creates a game and I I can not find this game as much as I create and it does not find my room.

We decided then download Hamachi "program that simulates the local network, we downloaded this program and we use it, I can not find his office and he manages to find my room, but before opening the game an error" gamestate - fatal error "( timer for 10 seconds and then he shuts the room and goes straight to the game homepage)

Can someone help me?
How to solve this problem?

Thanks
