I'm in the same boat. I've bought so many games from EA over the years and have never had to think about using Origin until now as my new laptop does not have a disc drive. Some of the games I've lent out over the years and have had to replace - using second hand games where possible to save money. Some of the expansions I've been able to add to Origin no problem - they can't have been linked to an Origin account before - both others have already been redeemed. Origin told me to ask Ebay for a refund, buy a new physical game (brand new obviously), or pay again for the game via Origin. It's a bit much that I have to now pay for a new origin key to play games that I've had for years.
@KmcUK1982 You could also look into sales from Origin and Steam to replace the content you're missing. (Steam includes a CD key for you to register with each pack you purchase, so you could download your content and add it to your existing game files through Origin.) It's still a bummer, but paying as little as $5 per missing pack (plus the base game, maybe another $5) hurts less than forking over the full price for everything.
