Have you put exceptions into your antivirus for Origins, DAI, and the DAI saves files over in your users folder??
This is the number one reason for the game to not start.
IF this doesn't fix it, then try disabling your AV and see if it works. ESPECIALLY if you have AVG or Avast, you need the exceptions/exclusions and sometimes to disable as well......talk to AVG/
avast why they can't figure out a 2 and a half year old game can't be known as a game and not a problem to be stopped.....
If this doesn't help, then post a Dxdiag file and system specs per the sticky at top of this forum......
