I guess you have install the latex-class correctly and made the lyx layout file correct :). There is another latex class from world scientific publisher in the wiki: http://wiki.lyx.org/Layouts/Layouts It states that you need to turn off babel support to make it work. Maybe your latex-class have the same requisites. If not we would need to see the errors to help. Ingar
