Unity Black Screen Editor

I need help, unity newbie developer here,
but I think there’s problem with my unity editor.
When I click play button, the editor screen goes black.

I already tried to re-install the unity 4.5.5, same thing happened.
same with 4.3.4.
Also I tried to check and uncheck “Use direct 3D 11*”, in player setting.

Anybody know how to fix this?

I record a video of my issue, please see link for details.

Go to Edit->Preference->Color->Playmode Tint, set this one back to white.

You probably tried to get yourself the pro dark mode but no can do until you spit the grand.
