Shadows appear on old projects but not new ones.

Hi all, hope someone can help me please i have just been trying to create new project using free version but can’t get no shadows even with a simple plane a cube a directional light and a simple diffuse material, i have checked shadows enabled in quality settings i have them enabled on light and even whacked shadow distance up to a million and checked ambient light but no shadows appear, but i can load old projects and shadows are working, i have closed and re opened unity and now tried making several new scenes but no shadows are working anymore, any help please ?.

Few extra things to check:

Object has both cast and receive shadows on,
Driectional light has bias set to 0.5

SOLVED i just unchecked the direct3d 11 checkbox in player settings and rechecked it and they have re appeared…
