If you are using chrome, look up in the address bar to the right by the star. There may be a little gray shield. Click that and hit "Load anyway." Unfortunately, it will refresh the screen and you might get a different HIT. When doing the dialogue HITs, I always keep an eye out for that shield before I do the HIT. Otherwise, their great HITs. You can do 20/day and 40 in a 4 week period.
