you can manually download default content zip (genesis Starter Essential) from your web account page,,
and install to your daz contents directory. but Have you installed DIM to your PC too?
it is beta tool,, but it make you simple to download contents from daz .
though you have not so many items at current,,^^
if you install and set up DIM, I think genesis Starter Essential , Modelator mentioned above, show as Ready to Download in DIM
in this puckage,, there are genesis (base default figure of ds 4.5) ,basic morphs, some clothings,, hairs,,accessories for genesis,
light sets , and shader etc.
after install genesis starter essential,, if you have some trouble,, you need to check CMS setting
(Content Managements Service is data base aprication, which manage and organize daz contents in ds,
so if it can not work well,, you feel difficulity to use daz contents)
actually you can do manythings with these.
I recommend you play around only with these free items and genesis at start points.
with looking you tube videos about daz studio 4, released by daz.
it help you lot to understand about each tabs.
and sometimes check,, where the contents files are installed,, then gradually learn daz unique folda structure.
the more you installed many product or free items, or different generation figure,, at once,
you may feel difficultiy to understand ,, how manage them. I think.
