Okay, so I know your post is old, but I figured out how to find the "my game tab"- and wanted to help other people find it out, because it took me a while, and a lot of stress to figure it out. Basically, once you download the orgin program, and make an orgin account, click the orgin program you just downloaded, and log in with the new account information you just made, at this point you will see the "my games tab", and the games you recently bought- just scroll over the game, and there will be a download button, click it, and wait, then enjoy! Hope this helped! 🙂
