The cause to this error is probably related to the compatibility. As I can see on the official website, the game hasn't been updated for a long time. In this case, the compatibility is questionable and because of that you might encounter issues while you run it in OS X 10.9.4. Unfortunately, there is no way to make it work when the compatibility doesn't exist. This is a known drawback when it comes to the MAC OS X applications.
If you have an older version of the game, download the 1.3.1 from the official website and then run it.
