Launcher troubles

Hey,
I recently bought a coupon for the game, downloaded a launcher but it doesn't work.
What should I do to solve this?

This menu appears and I can't do nothing about it.

 

Hey! Make sure that you move the application into your Applications folder. Because it's an unsigned application, the system will prevent you from running it outside of that folder.

 

OMG,
yeah it helped
thank you very much!
