Hi TrekkieGrrrl, I have got the same problem with this too ambitiuous software. I don't forget about P3dO but I sometimes forget about Poser. I have too many 3D softwares to look after ;)

Yes, P3dO now opens directly into Poser without the need of Prpc.
This feature is not related to P8. Any Poser is ok and I even managed to make it available with Poser Pro pack.
This has been made available with P3dO 2.2 (last May). I had to fix a minor bug with P8, this is probably what you saw. So you must have P3dO 2.2 (or P3dO pro 2.2 in your situation) and install the upgraded Poser Plugins Pack for P8:

As you can guess it is a fantastic improvement.
