I was the poster who wrote upthread about not having a valid reissued ticket by VS at check-in and came within minutes of missing my NH F award flight... have you thought about contacting NH directly and verifying your ticket looks okay on their end? If I had called VS prior to my debacle, I'm not even certain they would have caught the issue ahead of time. I think NH is in a much better position to determine whether you're holding a valid ticket for travel on them.
