Very large ad at obstructs and freezes play

[pokerjoker1]

I'm having a problem with a very large ad from "Maybe Happy Ending" musical on Broadway.
It not only takes up the entire bottom of the screen, it also obstructs the play area and then freezes the game.
It continues over and over again with video, etc. and there's no way to get rid of it.
It seems to happen when playing the monthly contest very early in the AM.
Here's a link to it. Thank you.
