Need help finding download for simcity 2013. Please help.

I purchased sim city 2013 a long time ago. I managed to actually log into what seems like my account on the ea website. I can see the transaction in my history. Where is the link to download the game? I bought that game 3 PC's ago...... I paid 80 bucks for it and also bought cities of the future DC. How do I redownload and install it?
