My GarrysMod menu and sound doesnt work!

Hello! Today I bought GarrysMod. I opened the game and clicked on (I just got my console on) the “Play Singleplayer” button and in the console it typed “Unknown command: menu_singleplayer” but some of the buttons works. I can play multiplayer but the Q menu doesnt work (The Q menu is that menu with the tools and stuff xD). So I really need help. I’m running Windows 7. So… PLEASE HELP! :smiley:
