Adding nodes turn object black Help!

I've searched on the internet for this issue but I can't seem te find it. So hopefully you can help me.

I have build an object in Blender, I want to give it texture and color so it can be implemented in Unity. 

As soon as I unwrap the object, added an image texture and give it a beautiful pink colour.



then, added nodes.



I hit the button "Bake". The whole thing turns black. 


It even happens with the default box.. What am I doing wrong?
You need to plug the Texture into the shader, then the shader to the output :



The color of the inputs and outputs is important. You can't expect plugging a Yellow output (Color information) into a Green input (Shader information), and get a result. More informations.

Also, in the blend you shared the texture is black, so of course the materal will be black.
