MM:S and SM not support listen server (server created in client game).
And you get more trouble by running addons+plugins from in-game, there are differences with srcds.exe and left4dead2.exe

What I try to tell,
next time when you have bug or problems with specific plugin blaa blaa blaa,
you should mention at first that you are running listen server and not source dedicated server.
Because there maybe not fix for that and we not need to guess how you run your LAN server.

I still suggest, use srcds.
