OpenSuSE Li-f-e 13.1 YaST won't load. Also I am a newbie

Hi All

HP G60 AMD64 Turion X2

Here is what I am doing. https://en.opensuse.org/SDB:Add_pack...e_repositories

Start YaST by clicking on it under Software in your menu

YaST prompts for password. I enter. Then nothing. No error messages. Nothing at all happens. So I open terminal and at the command prompt type: sudo yast

root's password:

Enter password and returns to the command line. Nothing happens.

I am sorry I cannot supply any more info than this.

kind regards,
bill
