Playing the Game...

Hi, I've bought and used a digital download of Star Wars Battlefront off Origin. All went well, the game downloaded just fine and the game started up okay, nothing wrong just yet. But when I went to actually start the game as it instructed to "press to start" on the opening screen, nothing! I imagine that you have to press "return" on your keyboard to get the game playing but nothing happened and I can't play the game at all..... What can be the solution to this problem? Any help is appreciated.....

Thanks....
