I’m having the same problem. I reinstalled the game but it’s still doing the same thing. Just click new game and it does nothing.

Ah, your save file may have gotten corrupted. Go into your Appdata\Local\AtC_BB\Saved\SaveGames folder and delete the .sav file. After relaunching the game, it should create a fresh save file and hopefully fix the issue. You will unfortunately lose your progress, but the game should function properly now.
