Focus - your current score is 791, even with a very recent 60-day late? That's pretty awesome. Means your score before was 'prolly about 820+.
Yes. Call them and explain what happened. Folks like you don't achieve sky high scores by being late with payments. They should understand. I've never had a 60-day baddie, but did have a 30-day baddie 4 years ago, and a GW worked.
Good luck.
