Can't register the Sims 3 on origin

[liekefriet]

Hey, I bought an original game of the Sims 3 in a store. I installed it, registered it, everything worked fine. Now for some reason Origin is asking me to activate the game again by entering the product code, I enter the code, but it says it's wrong. Then it says to register the game on the Sims 3 site, but there the code I enter is also considered wrong! I don't know what to do
I thought it would be fixed if I delete my origin account and reïnstall the game, but now I find out here in the q&a that you can't delete your origin account.  Please help me!
Thanks!

If you delete your account, the game will be gone and you can't reregister so don't do that.

I would contact customer support so they can take a look at your account
