[localhost] (NUCLEUS) service is not accessible

I have been running fine with the localhost nucleus server set up on an SSD second drive for weeks now. This was a requirement for Reallusion, and so far so good until this morning. The interface from iClone 8 to Omniverse does not work for light and fire. So I spent all day yesterday adding lights. I got 7 out of 10 first created, but the 8th would not light. Finely I left the program and shut the computer down for the night do to storms. this morning it came up fine and I resumes my work on fire 8 until the screen when black and the computer locked up and a Hard ReBoot was required. After that I no longer have the localhost loading. Even with a restart, It fails to connect to the authentication service.

I checked my E drive and there are files dated for yesterday and this morning… up to the crash… I am hoping no work is lost and that somehow something is missing from startup.

I am afraid to re-install for fear of losing this project.
