Recently bought Far Cry 3 and Assassins Creed:Brotherhood, and something strange is happening.....The game starts up fine and the initial videos for both work etc. but then when the actual gameplay starts my keyboard just doesn't respond, the mouse works fine and I can look around and click etc. but the keyboard does nothing, although all the normal functions i.e. pressing alt+tab and ctrl-alt-delete work fine! Anyone know how to solve this as I'd really love to play these games soon!
