I just got my Poser 5. The service packs are not on the CD, and I wouldn't expect them to be -- EVER. I bought Poser 4 and the Pro Pack long after the last service packs were released, and none of them were shipped with the product. In fact, I purchased Pro Pack as a download from the CL store, and I still had to download the service pack for PP. By the way, Poser 5 has run without a hitch on my machine under XP Pro. I'm really excited by the possibilities, but there are enough changes in how things are done to require a big time investment in learning the interface again.
