I downloaded the patch to update Q4 to 1.4.2 and Q4max .78d and it said i need the pk4 file called zz-q4max-game-078d.pk4 which i downloaded from google and put it inside q4max folder but when i play the demo it shows the loading screen then just goes back to the menu. Anyone have a solution to this?

These are the other demos i would like to play -
