Windows 7: Hamachi

Hello, I would like to play games online with my friends via Hamachi application. If someone of us create a game server, others can't see that in Lan section. For example, we tried to play counter strike, call of duty 2 and so on...Have you got any idea how to fix it ?
Thanks.

have u managed to create a private network? then search for that on each computer. would that be the way for this? havent used hamachi

How can I create a private network ? I don't have such choice. I can just create home, work, or public network.

sorry i ment a private network for you and your friends, create a public network and then join there, dont forget ur shared files will be on ur friends network as it creates a virtual lan when you join the network.

Hm, I just set Hamachi as a public network, but what after that ? How can I join there now ?
