Use of this project in new Unity 4.3 2d feature

Hello everyone ! I am very new to Unity ! I am working on a basic 2d game which requires the calculation of the minimum path between 2 points. I tried to apply the “getting started with A* pathfinding project” to the new 2d feature of unity 4.3. But its not working. The AI object is going all the way down to the y-axis and i cant even see the path drawn. But i am getting all the messages in console properly. I have also attached the screenshots of layout and grid graph settings.
Any help/suggestion/insight is greatly appreciated !

Thanking you !

If the character is falling straight down, it’s likely that you have gravity on. Turn it off in Edit->Project Settings-> Physics/Physics 2D.

Thank you for the reply ! I tried, but its not working. Also i haven’t added Rigidbody2D component to it.
