I have a problem with the single player part of the game, whenever I turn on the vanilla single player or an sp .bat file the console that pops up while loading the game normally goes through the files for a second or two and then stops and says:
z_free(): corrupt zone header!
if possible i would like to know what this means and how to solve it
