Any newly created runtime must be linked first to Poser before it is actually "seen" be the library.  Clicking the Add Runtime folder on the upper right side of the library will guide you through the steps.

As for Genesis, since it does have it's problems exporting from DAZStudio to Poser, there may be little interest for Poser based characters.  I may be wrong, but the trend now is leaning away from DAZ based Poser content.
