Hi wrpspeed, I am Yarp the auhtor of P3dO.
With Poser 8 (and all other Poser too) you should not use Prpc anymore. Instead P3dO is using direct open mode.
That is you do not open Prpc in Poser but when you double-click a Poser file in P3dO it opens in Poser.
In order to use P3dO like this you have to look at PoserPython options in P3dO Options dialog, Plugins tab:

CHECK   Double-click Open in Poser
UNCHECK Use with Poser Remote Procedure call

Appart from this P3dO is constantly updated. There has been 3 updates since 2.2.5 but I uploaded none at Renderosity because it takes time to upload, write articles for the upload, prepare pictures. I am alone, it's way too much work for me, so I upload only once every 3/6 months here.
But those who want to get informed of updates may activate the Automatic updates notifier in Options dialog, P3dO Online tab.

Then If you have viewing problems there's a terrific option for you in P3dO 2.2.8 that will stretch Poser thumbnails to larger dimension.
The free version of 2.2.8 is not available yet but you may use the unregistered 2.2.8 with no penalty (you'll just see some grayed features that are otherwise hidden in the free version).

btw P3dO will celebrate 10th anniversary next month
