well as far as im aware your just not downloading the files needed. you need to go into your options, choose multyplayer and make sure in the bottom right it says "allow all custom content" or something along those lines. then when you rejoin the server you will download it all and it should work.
also note that Episode 2 is needed for most of the game content,maps and tools. I dont think its needed for the menus but it is for the gamemode to be playable really.
