I found the same confusion with the versions. I purchased the P5 version and yet the installer says it's Poser 4. I even double checked to be sure I had purchased the correct one. Who knows! Frankly I have not been able to really figure out how it works yet to get the effects Paul does. So for all I know I might have the wrong version installed. Who knows. That's why I was interested in the update....and the tutorial. The presets from that 2/14 update might be useful as well....if all else fails :)
