The trial and the default installer on the DVD both only include a limited number of templates, due to file size. When installing CorelDRAW Graphics Suite X4 from the DVD, you can go to the extra tab and choose all the templates, content, ... to be installed on your computer. Alternatively, you can install the templates and/or content separately by using the extra installer on the X4 DVD (I believe it is the second option in the auto-run window).
