I bought the pets expansion, but it was a origin code and not the disc. I redeemed the code on origin and it said it is installed. But it will not let me register the game also on my ea account page. The icon's on my player page shows I have the game (Pets), but it will not let me load bonus content for the Pets game - I get the error "must have Pets 3" to install/use this content.
