Being a complete novice at this, and at the risk of appearing stupid because I've missed something glaringly obvious, I am sure somebody can tell me where I'm going wrong.

I have Daz Studio4.6 with Genesis, Genesis2 and Victoria4.2 to play with. Not wanting to shell out too much money I haven't got on something I don't if I'm going to take to, I downloaded a few bits  from here and unzipped the packages into the appropriate file.

However, whatever I try to use from these files, I get the same error message that DAZ can't find the appropriate .dsf file

Is it me? Is it the DAZ software? or am I missing something stupidly simple?
