Hello! I'm new, to both game and this site.

And i have a problem with connecting to a friend's hosted LAN game, it says:

Could not reach game host
The Network socket could not be created
The Network socket has encounter an error and was closed. Disconnected

The third error when i try host a LAN game (as well as with Direct IP Connection)!

Can anyone of you help me through this problem? I have the latest patch installed... disabling anti-virus or firewall won't help,
i read it something about proxy and IP, but i don't quite have enough knowledge about proxys.

My software are COMODO Firewall and Avast!-antivirus. Anyone used these, so one can tell me what to do to fix my problem with LAN gaming? Is it Hamahci or what? Please help... :(

Really, can anyone help me wi this issue? :(
