Gah, don't have Deathmatch source, don't see why its relevant.

I tried downloading this from Gamefront and I extracted it to steam>steamapps>sourcemods and it showed up in my Steam library at the bottom, whenever I launch it though it only opens the game up to the Valve logo with the head with the red valve and maybe even a look at the Zombie Colony page, I don't know whats wrong but if anyone could help me out I'd much appreciate it, ADudeWithAHat on Steam.
