What do you mean no loose files? If I click on a mod there is just files in there most of the time and not folders.

This is what is said word for word, " server script compile error unknown function ss thread maps\_zombiemode_powerups:: special_poweup_drop[ss orgin]

Do I type that in the console?

Just recently whenever i launch a mod to play I get a server script compile error (please see console for details) I dont know what to do please help me.!
