Weapons stopped working

Nice game, guys, but I’am facing some weird bug - I’ve reinstalled OS X on my Mac. Then I’ve successfully installed the game again, chose to use iCloud and successfully loaded the game. The bad thing is that somehow I just can’t fire any weapons. When I press keys 1 to 4 I just switch between weapons, but they won’t fire both in real time or pause mode. Reinstalled the game, removed all hidden game files, did whatever - no luck at all. Please help.
