Cannot scrape 1 movie - Lonesome Dove - odd error message

I cannot get my copy of Lonesome Dove to scrape. I had it scraped fine, then made some adjustments to movie sets and then started getting error messages. I'm on newer Win7 machine with the movies on an HP Media Center Server.

My error message comes up when I send MC to scrape just the one movie.

Then I get...

Error Encountered at stage 16
System.NullReferenceException: Object reference not set to an instance of an object.
at Media_Companion.workingwithnfofiles.savemovienfo(String
filenameandpath, fullmoviedetails movietosave, Boolean overwrite)

Huh?
Can anyoneinterpret this for me and tell me how I need to handle this?

Thanks in advance!
