The path to Poser as Richard explained was left over in the database from the first time you installed. I can't help you much there, as I manually manipulate file locations of my files and load them through the content manager rather than smart content. I would de-install the lights using the Download manager, then re-install them. That should clear the erroneous database entries in the metadata. You shouldn't need to reinstall anything else, your program set-up is fine at this point.
