I have Platinum Club membership as well, but so far I don't like what I see regarding Victoria 5 and all that troubles just to get it to work in Poser, IMO it's just too expensive unless they produce a Poser compatible version. I've tried the free version of Daz Studio before, never quite liked it.

There's one more thing, is V5 based on the Genesis figure? If so then V5 certainly will not work in Poser, since Genesis is a Daz Studio exclusive figure and so are its derived figures as well.
