It sounds like there might be something blocking the game from starting up correctly. Have you had the chance to try starting up your PC in a Clean Boot to see if that helps at all? If there is something else running on the PC that's not allowing the game to launch that may help get around it.
For more information on how to set one up check out the EA Help website. Let me know if you're still having any trouble with the game not starting after that. Thanks!
