I can verify that there is an absolute path mistakenly left in the .duf files. That's what's causing the error. You have two alternatives to correct the mistake: either change the texture path in the surface tab for both the diffuse and bump channels and resave the assets back to the Daz library, or physically edit the .duf files in Notepad++ and resave the corrections. I opted for the latter method; it is tedious looking through the script, but I avoided going through the additional steps to save it back into DS.
