If you take a good look at a "default" Poser installation (stuff installed just as it came from the store), you might be surprised to find a baffling assortment of errors. I swear, even the "big name" online stores just don't seem to know what they're doing. In the end, it's better to start all over. Of course you need to have your Poser stuff, in its original format, already backed up. And you'd want to get CorrectReference Pro. Install Poser, then create temporary folders to install your new stuff.. Look at each item by itself, and make any changes necessary. In fact, you might be better off getting rid of all those folders with the artists' names on them, and creating your own folder structure with names that make sense to you. Once you get stuff installed, use CorrectReference Pro to handle any references that have been changed. When you're done, your Poser collection will work great, and make sense. You may be surprised how much faster Poser works when you have things setup right.
