Problem with yast

Last night I tried to update my system, and when it was 63% done I aborted the update. Now when I try to run any item from Yast Control Center it gives error like this:

yast got signal 6 at ycp file wizar.ycp:688
/sbin/yast2:line 421:4472 Aborted
$ybindir/y2base $module “$@” “$SELECTED_GUI” @Y2_GEOMETRY $Y2UI_ARGS

Plz help me to fix this.

My system;
opensuse 11.0 x64
amd 64 3000+
