Redeeming the Humble Bundle codes on Origin
So, I bought the Humble Origin Bundle,as you probably guessed by the title. Being the impatient fool I was, I redeemed all of the codes in Origin, via the Redeem Product Code button, including The Sims 3 and its expansions that came with it. I encountered an error upon startup, preventing me from playing because my game wasn't registered on the official website, thesims3.com. The day after, the instructions for redeeming The Sims 3 came up on the Humble Bundle and Origin website, which I followed, to try and get the game working, but now, whenever I try, the website says the codes are invalid, because they've already been redeemed. So now I have a copy of The Sims 3 and two expansions that won't work.
What do I do?
P.S Tried contacting customer support, but for some reason, the chat windows don't display any text for me, and besides, living in the U.K means it's almost impossible to get on at the right time.
