Shadow Demo in Unity 3 Pro

Hi I have been trying to add shadows to my project but I just can make them work, I even downloaded the Shadow Demo… it looks great on the Unity web page, but when I open the project the shadows don’t work… I already have checked the project settings and I suppose that my video card supports them since I can see them without problems on the Unity Web page… I have Unity Pro license… any idea?

Finally I found the problem… I selected the main camera and changed the rendering path from User Player Settings to Deferred Lighting
