I'm using whatever comes with MicroSerf XP. I reinstalled everything from scratch and realized after the second time there are 2 P5 folders: one is Poser5... the other is Poser 5. You cannot delete either of them (as I did the first time thinking it was my download error). I think this is the same nonsense as the character and characters files found under Runtime.

I can see right now this is going to be confusing as I try to reorganize my files so I can start using all my old Runtime files again.
