Help?

I looked back through the past 10 days and didn't see a game that you won with no rating change. I did see two games that you lost with no rating change, both times because your opponent had a rating much higher than yours (both games were set to be rated). It's unlikely that you'd have an opponent with a rating far below yours, so if you did have a win with no rating change it must have been a game that was an unrated game, and you didn't notice that setting when you started the game.
Can anyone tell me what's going on? I was playing a game the other day and after I won my blitz rating did not change?!?!
