The game hanging at this point is caused by a third-party UI library, called Coherent GT, not responding while the game attempts to initialize all its UI assets. Unfortunately I don’t have any insight as to why this may be the case for you, and with no means to rectify the situation, I’m afraid the best course of action for you may be to refund the game.
As for your other point, Awesomium isn’t our engine. It’s another third-party UI library that Battle Brothers made use of back in the early days of the free combat demo, but which was since dropped.
