Control File Editor: "No modules available in this group"

Hello, I freshly installed SuSE-8.1 from CD on my Installation Server. Then I created a software depot, installed all current update-rpm's and used '/usr/lib/YaST2/bin/create_package_descr' to update the new package descriptions. When I tell him '/sbin/yast2 autoyast' I get the YaST2-GUI but when I try to create a new control file and then click on "Software" he answers 'No modules available in this group'. The Package Directory has been set correctly under "Preferences". Or do I have to use a SuSE-8.0 AutoYast in order to create control files (it works fine with SuSE-8.0)?! Thank you very much!! -- Erik Soyez
