Re: Invalid product key
@drdingledumb You'll need to contact EA customer support and ask that the game be added to your account. Or, I guess you could refund the game from Steam and buy it again, hoping that this time, you get a valid product key.
If you do contact EA customer support, I would strongly recommend using live chat rather than email. If you don't see the option, try this link:
Make sure you're signed into an EA site (this one is fine) before clicking the link and that the location in the lower-right corner of the browser window is set to U.S. or U.K.
