Invalid Product key NFS Most wanted when trying to re install

If you didn’t buy your game on Origin (or if it's not a digital copy), Origin should be included in the installer for the game.

You should be able to re-download the game via your Origin client ( the application.)

If you have not done yet, visit this link  www.origin.com/download to download the latest version of the Origin application for your desktop. 

You need to use the account you activated it on.

And you don't need to enter the code again since it's registered to the account you used. If you break your DVD you can download it again too instead of using the DVD.

For some reason my copy all of the sudden dissappeared from my Origin account, but was still on my computer, asked for my code again, it said the code was already used, why???? it just asked for the code again... Please help, this is the last way I can play Most Wanted because my PS3 copy dissapeared... <:/ Help. I ordered my game as a disk from Amazon.com, and it was working fine until my account seemed to have just removed it for no reason. It wants me to reactivate the game but it won't work. Please help. I don't want to buy my game again, it wasn't cheap. Please help! I assure you, I didn't do anything. I was inactive for a bit, and if that is what it is, please help. ):

i logged in using same account but even though im not able to c my game
