Hey guys i just installed arkham city onto my computer and i find my input devices like keyboard and mouse are not working. I can navigate the menu using the mouse but i cant use the keyboard. Also i have tried using a Xbox 360 controller to play it sorta works in game but no really. I cant navigate the menu with the controller which is a pain and in game the cut scenes and animations where batman picks up new gadgets with the A button is not working. Also after a while the UI on screen will disappear leaving me with zero control forcing to close the game with windows task manager.

I spent good money on this game and i really want to play it but with these controls problems it makes the game unplayable.
Please help me come up with a fix.
