Ubuntu 11.20 launcher disappeared after installing Nvidia Driver

Yesterday, I have installed and updated Nvidia driver from Ubuntu Software Center. After restarting my PC launcher disappeared like in screen:

I have restarted, updated and re-installed Unity. But it doesn't work for me. I think there is problem with graphic/nvidia configuration.

I have removed Nvidia (current) Driver from Software Center. It solved problem but I feel it's not updated driver which I'm using now?
