I am making a first person game in Unity and when i load the FPS control package thing form the store onto my Assets, i put the camera thing on my map but when i try to run the game it says i have to fix all compiler errors. when i look at the FPS controller in the inspector it says under the scripts that the associated scripts cannot be loaded. what do i do?

Also, when i try to run it without the FPS controller, it says:
