YAST won't open in SUSE 10.1

5.30.2006 I have read all the email regarding problems with YAST. I have managed to update installing / using a command line utility which can update / add repositories. Unfortunately, I still cannot open YAST. Worked fine in 10.0. Upgraded to 10.1 and, it wouldn't open. As you know, YAST does a lot of things besides just package management so it would be cool if I could actually get into it. Sigh. Anyone have any ideas. Would be most grateful.
