A simple face (you had extracted) worked just as the regular Area light - only four vertices. I'm supposedly making nothing if I reach this condition. Supposedly because (I don't know if you have noticed) the shadow is in the opposed side of the cube.

It was good play with your file - I found some issues I couldn't find before by using cubes or spheres.
If you cut the four edges of your lamp (select and hit 2), then it will be treated as a mesh lamp and the shadow will be displayed in the right side of the cube. But, if you make it bright (playing with Ambient values) you will notice that the plane is now rotated.

I'm doing something wrong yet.
