If your external libraries already exist, run the script Import Runtimes 2014 under Scripts>Partners>ShaderWorks.  That will automatically link all existing libraries to the Poser Library.  

And if you are running Vista, Win 7, or Win 8, did not place any runtimes within Program Files.  You're original Poser content should also exist as a separate runtime called Poser Pro 2014 Content.
