I uploaded the IHM .vpk file to the addons folder of my server. When I'm in a lobby, after using the mm_dedicated_force_servers ip command, I want to join my server but I can't connect. I can connect if I select a stock campaign. It's been a while since I set up an L4D2 server, so please forgive me if I'm missing something easy...
Well sorry, we don't provide dedicated servers support. Mostly because we don't know anthing about it.
I don't understand.. how else would you host a game for this mod other than on a dedicated server?
