Problem working with Essional Studio in design time in the VS

Hello, I download your essional components for windows forms in trail mode and I can''t working with this in the visual studio. Just after using your components, I can''t write something, I can''t change the component the properties or delete it just after reopen the VS. The keyboard was working and I was in design time. The problem happened just after using your components in another components it''s working perfect. The seccond problem is the licence. I download the trail version and I don''t have any announcements about the trail version it''s seems like licenced version. I don''t know if it''s problem but maybe the first problem to be caused by the seccond.
