lan

Hello, i'm sorry for my bad english. I have a problem when playing LAN. My friends can be host and i can join his game trough LAN. But when i try to be host, why my friends can't join my game?

I start the game in lan normally, my friends connect, but in the middle of starting the server-game simply closes alone, what problem? We test both the panoramaui and the scaleform and give the same error. Version 1.36.4.6
