First Person Controller Scripts Are Not Working!

I can't enter play mode in Uniy 4.3.3 because all of my scripts for the First Person Controller have compiler errors. However, I am only using the default scripts that come with said controller, and have made no changes to the scripts. I have no experience with JavaScript or C# and have no clue on how to solve this. I have tried re-installing Unity, and I have tried moving the CharacterController package from one project to my current one, but that has made no difference.
