Steps:
1. Beat RoV 3-17 and the game proceeded to a series of scenes for RoV mission 3-18 "Sin"
2. Computer disconnected from the internet
3. Resumed gameplay only to be stuck on RoV 3-18 "Sin" unable to further progress
4. Click on the 'Transcendental Radiance' in zone 'Desuetia - Empyreal Paradox' and receive the message: "You see innumerable stars shimmering in the distance..."
5. Click on Cait Sith and receive the message: "I shudder to think of what might become of this world..."
6. Summon Trailmix gobbie and he allows me to rewatch the scences: "Death Cares Not", "No Time Like the Future(pt.1).; "Sin(pt.1)."; Sin(pt.3),"
7. Click on the "Mystic Retriever" in Port Jueno (as an act of desperation) and nothing happens
8. Current active mission for Rhapsodies of Vanadiel: "Sin"

If you d/c mid cutscene, you go to the mystic retreiver, which you did, so you assume the cutscene played enough to consider it finished. Do the next step.

Return to Reisenjima Sanctorium for a cutscene.

It worked! thanks!! I spent over a year away from the game for a silly reason, doh.
