I ran into the same thing earlier this week and so called Viking. They looked at my flights and saw that Delta had delayed my last leg of my return flight by and hour and that is what caused the message. As it was the last leg, it did not necessitate any additional changes (i.e., impact connecting flights) and so they were able to clear the message and let me immediately see the flights through MVJ while I was on the phone. Very friendly and easy and took less than 5 minutes, so I'd go ahead and call if its not fixed.
