I have just bought on Origin The Sims 3 Ambitions. The game won't download and it says I need to install the service pack of the Sims 3, but I have already got it on CD on my desktop. It also won't let me download the Origin like it says I need to, there is no response when I click on the download button. I want my money back please.
Have you tried to install your The Sims 3 base game and all your packs through Origin? That should help you avoid this kind of issues, as it's better not to mix DVD and Origin versions of the game.
You can download the Origin client from here: https://www.origin.com/store/download
Regarding your refund request, we can't help you here in Answers HQ with that. You would need to talk to one of our advisers through EA Help about your options. You will find a detailed explanation on how to contact them if you need it here.
