Yes, Billboards are always facing camera. Good for making all kinds of flares and distant objects like trees.
Where do you get that "constructor" message? Is it a warning shown in Max? I don't think I've seen it.
What I've noticed is that it's a good habit to delete the previously generated prp files before each export. If they're not deleted sometimes textures don't update, and Dustin's converter starts to generate warnings (it says they're internal, but anyway).
