opensuse 11 kde 3.5

Hi,
I pretty new to openSUSE. I have installed opensuse 11 kde3.5 . Everything went fine. But when i want to enter system and would like to change there something, or open yast or run updater, i always have an error. Any solution?
thanks

What does the error say?

application-system-configuration-configure x11 system then sue returns with an error

updater - install update then sue returns with an error
The funny thing is that when i have only tested the program with liveCD x11 system configuration worked. Then i installed it under xVM VirtualBox
