Hello Igor,
Thank you for your timely responses ~ I figured it out.
I was using the Identifier. However, it turns out my error was due to the name of my Universe. It looks like it uses the filename instead of what I have it named currently in the Universe tab. Initially, my Universe was named "Ryan's Universe" and upon receiving your initial instruction I simplified it to "Ryan"...it wasn't until I checked the object tree that I notice the original Universe name/filename was being used (Ryan's Universe).
