Missing .dsf files

in New Users
Hi :)
I have this error that Daz3D's .dsf files can't be found. (anyway, I have the Daz3D in other PC and it works).
I saw 'Contect Directory Manager' in preferences and everything looks fine. But when I go to the folder on docs, it's empty, nothing there. So, I don't know how, I missed the .dsf files.
Can anyone help?
PS: Sorry, English is not my first lenguage

Could you post a screen shot of your Content Directory Manage dialogue showing the folders listed under Current set > DAZ Studio Formats, and of the Installation tab in the Install Manager Preferences (gear icon at top-right) if you installed with that. Where are the .duf files you double-click to load the item?
