DAZ|studio comes in many versions, stuff made for later versions won't work in earlier versions.
I found version 1.7 onwards crashes on my machine, but 1.4 to 1.5 were fairly stable, so I keep
to 1.5. This means most stuff now made for DAZ|studio is no use to me, but I can usually find
a way to make Poser content run crash-free. So, keep to the many Poser freebies available,
try them out, if they ain't no good you don't lose anything!
My Poser runtime is huge, I have very little D|S content at all.
