Quote - The Poser8 Content folder at the top of my screen says (when my curser is hovering over it) that its coming from my Documents folder, which is not where I installed my runtime

Right, that is what I was getting at. Somehow you corrupted the main runtime entry, so that Poser does not actually tell the truth about where the main runtime is located. So of course the GUI couldn't show you anything from your main runtime, because it was told the wrong path, and so nothing exists in it.

I believe the script you ran to add external runtimes is, itself, buggy, which led to you gaining your externals and losing your main.

You should hand edit the libraryprefs.xml file and restore the first entry to have the correct path to your main runtime. Otherwise, more things will be broken than the library GUI.
