Maybe this will help.  If you do find previous purchase at Daz, do not use the Daz Dl manager...Install manually  to your poser...you will also need all the morphs etc..

System was purged so even though you purchased they will not show up in purchase content :( .... 

Also something I found invaluable. When you install .Open up V4...search for ++morphs....Add all to the figure....Then save..........each time you use her, adding outfits etc. change file name to what ever you added....

Not a poser pro but found above works for me.
