It sounds like you did everything right. I cannot get into Daz at this time I am in the middle
of a render that will take a few days.
You need to be sure that Daz knows were the data folder is.
Off the top of my head I do not remember were I set that..
I will check as soon as I can.

In the mean time check and make sure the data folder is in the content folder
and the directories are located properly in the preferences in Daz.
The scene files should open with no problem.
