World Sceneries, Conganhas Intl problem

Hi, Had purchased this scenerybut I have problem installing. I followed instructions for install but keep getting error message. Strange thing though, when I start simulator default scenery is there. But there is thing to uninstall scenery. I try to add scenery through settings in simulator, but do not see it located in any folder. Only thing is Wsuninstall. I contact developer, no answer.
Anyone deal wit these people before? Anyone have this scenery? Thank you for your help, jakob
