Yast dies with Online Update

I bought the pro-office patch CD but can't get it to install. YaST dies when I use any software module. Online Update dies with "/sbin/yast2: line 154: 2850 Aborted /usr/lib/YaST2/bin/y2base ncurses" Patch CD Update gives this error "/sbin/yast2: line 154: 2606 Aborted /usr/lib/YaST2/bin/y2base ncurses" Any help would be appreciated.
