I think I sort of figured it out. I redownloaded in case of a corrupt file and looked at the lights. They all say Poser 7 content. This set was designed for Poser 7 . Also, all the lights are parented to something in the room - the inlcluded furniture - even though there are settings for "ambient light - room empty"  The empty room does not light up unless you load a bed or some prop, then the lights work. Then, if you delete that prop the lights still work but are not as bright. You CAN'T load the empty room and light it without a prop in the room first. An included prop - not just Vicky. Very, Very weird.
