Installing KDE 4

I want to install KDE 4 (I’m using Gnome yet).
So I clicked on the 1-Click-Installation here.

The first and second step work, in the third step I have to enter my password for the Yast Package Manager Module. Then I come to the Package Manager. And that’s it.

The installation windows says: “Software is being installed, please wait”. But even if I wait 10 minutes, there’s nothing happening.

If I close the Yast window, the installation window shows me an error.

As a first suggestion, ten minutes isn’t long enough. Each time I have installed KDE4 as a separate exercise, it has taken 25-40 minutes.
