Hi Danny, I understand this can be frustrating, you are right the help link is pointing at invalid URL at the moment. We do have a fix waiting for deployment, I apologise for the incovenience. Please go tho the DesignSpark PCB home page http://www.designspark.com/page/DesignSpark-PCB-Home-Page and watch the ModelSource interface video. This explains how to use the new libraries, in fact you fo not need to look for them in libraries as you can just dran and drop directly to your design.
