I've downloaded a handful of maps and installed them in the specific directory (...cstrike/maps) but in the game when I try to create a server with these maps (be it online, offline, or lan) they do absolutely nothing. I hit Create Server and the window disappears but leaves me at the main menu with absolutely no error messages. But the standard Maps work perfectly fine. And even from in game when I try to make a server it will only disconnect me and leave me at the main menu again. The files I have are .bsp and .nav, and are for Counter Strike Source. Any Ideas?
