Activation Required ON A GAME I ALREADY HAVE AND PLAYED

[atmur]

I have Need For Speed Most Wanted 2012, and have had it for a couple weeks now and I've played for about 3-4 hours maybe, and I tried playing it again and it opened a pop-up saying "Activation Required" so I select "Activate Game" and put in my code for the game and it says "This code has already been used" Yeah, BY ME.
If someone could help me with this that would be great, thanks.
