Unity White Screen Problem

Hello, i just installed unity today, but there seems to be a problem with my unity. When i started the program, there is nothing but a window with white background. It happens after the license manager and Project Wizard, i dont know what seems to be the problem.

I have tried reinstalling the program and uninstalled RocketDock as suggested in the other question which have same problem, but none of them worked.

I’m using Unity 4.6.3

This is the screenshot of my desktop:
