Custom Movement Script Not Registering Input

I am following tutorials to create a third person script and I have encountered a problem.

With any custom movement script, inputs are not registered and I cannot move. But when I add on the example third person script it works fine but as soon as I modify it, it stops working.

I have tried all of the documented "remedies" but none of them work. I can't find the Input registry , nor does maximizing on play work.

This problem only seems to happen in unity 5.1-5.2.2

I really need help on this, any help is appreciated.
