Can't create object ZombieGorefastBase1

Hi



For some reason, whenever I try to start a server or start a game, the game crashes and gives me this error. I've tried to fix it by verifying on steam. It said that I was missing 1 file and it would be re downloaded. After trying again, the problem still persists. This game ran fine just last week.
