I've got the same problem as Simsane. The add is for "Libertex online" app and now will not close (there's no x to tap to close it, there's only a replay button). Seems the only way I could close it is to install the app, which I'm reluctant to do. I don't live in US, I'm from Europe.

What can I do to get rid of it? Have tried closing and re-entering the game, but the only thing that does is get me back to the add. I can't play at all.
