Hi, I know it's not origins forum but I hope you can help me. have downloaded and installed the DLC and I just can't start playing it with my origins copy. Do you know what's the problem?
Try checking for a patch or clearing your cache and redownloading all updates for the game. Most involved "connecting" DLC so that might be the reason. I'd avoid the DLC even if you love the game, it is not worth the cost or grievances.
