Stealth project problems: big problems after importing

I had a working stealth project fully complete quite a while back, but I wanted to import it into another project so I created a unitypackage file for the stealth project. I imported this into another project and I got three errors. One was for the char_Robot.

navmeshagent.velocity assign attempt for 'char_robotGuard_001' is not valid. Input velocity is { NaN, NaN, NaN }. UnityEngine.NavMeshAgent:set_velocity(Vector3) EnemyAnimation:OnAnimatorMove() (at Assets/Scripts/Enemy/EnemyAnimation.cs:51)

That was the first error, the second error was on the PlayerMovement script. The player was not moving and I got an error in the console.

Input Button Attract is not setup. To change the input settings use: Edit -> Project Settings -> Input PlayerMovement.Update () (at Assets/Scripts/Player/PlayerMovement.cs:51)

My final error was that the camera screen was all black. We could faintly the player and the environment.

I am using unity 4.5 and am following the unity stealth tutorial at:

http://unity3d.com/learn/tutorials/projects/stealth.

I also have an attatched screen capture of the errors.

Is there any setup that I have to complete or any wrong way I imported the project? Once again I used unity's importing custom package feature to import files. I am using the free version of unity.

Thanks in advance.
