Well, I'm in the same boat as Irish. Nothing I got from C3d will work in Infinite because it was purchased for Vue 5, and that is annoying to say the least. However, I'm patient and willing to wait as I'm just a hobbiest and not professional. :) Having said that, I agree with Irish, if DAZ placed that kind of restriction on Poser items (I have 4, 4pp, 5 and 6) I would be thoroughly torked and refuse to purchase any of their content.
