Unless you fix it yourself , probably not, the last update of the asset was (Sep 25, 2013) build for 4.2.1.
You can try to contact the developer but since it its a free asset it’s unlikely that he will fix it.
If the Asset is broken and is not showing up, you should check the console for errors.
That is the issue, there are no console errors. Because of that, there is no way of telling what is going wrong. Is there another way to check for bugs in Unity?
