ACB PC : Any command doesn't work in the cutscene | Forums

[anashtree]

I'm Korean, sorry for my poor English

I just bought AC Brotherhood in steam and installed it
My mouse and keyboard works fine in menu screen, but when I enter the first cutscene, the attack button doesn't work so I cannot play the game
I already re-installed the game 3 times but nothing changed, so I guessed that's my mouse's problem and changed the attack key in settings, but it didn't work...
All I can do is just push ESC and exit the game
How can I fix it?
