What content ?, a link to it might help.

DS4 has 2 ways to display content, the Smart Content tab and the Content Library tab, Smart Content is a content manager database that requires content without any Metadata (only DAZ supply this on new products atm) to be manually added to it before it'll show. The Content Library is the old way (and still the best way IMHO) to view your content, it shows it as it is on your harddrive and doesn't require you to jump through hoops to get it to show.
