Oh! I was so hopeful when I saw that you'd posted!!!
Oh well...
You know my answer to many things... On your 13th (or so) day of classes, clear your cache AND cookies. Then do days 14 and 15 (I suggest clearing cache & cookies on day 13 in case Recess comes early. I think it should be done before you take the last day of classes.)
I hope your badge shows up soon.
