Pay with a like is not working correct!

https://premium.wpmudev.org/project/pay-with-a-like/

Ok have tested 2 plugins and 1 theme. And all have been broken and not working. And here comes a new error plugin. This one i realy was hoping that it should work. And it would be fun to have.

Pay with a like.
I have installed this on the latest wordpress. And I use the latest IE, Firefox and the latest Google chrome. Have tried all browsers and it will not work with Facebook button. When you press the like button on this. Then it's thought that this box will disappear? But it does not. Good thinking there, but this does not work either.

Oops! I forget i dont have any conflict with any other facebook buttons on the pages.
