Rigidbody fps controller stopped responding after update to unity 5.5

I’m doing a project for a client. My Rigidbody fps controller was working perfectly.

Then, I updated the project from Unity 5.4 to Unity 5.5.0f3 today.

And suddenly my Rigidbody fps controller stopped responding.

I updated the Standard Assets in this project to the newest ones. Added a new Rigidbody fps controller, but it doesn’t move either…

I am supposed to deliver this app today! Does anyone have a suggestion?

Bump. Any ideas guys and gals?
