SIMS 3 Base Game is Not Opening

I've read the instructions on the Mac guide. (I have a MBP April Mid 2010 10.9...) I have a Vuze torrent and I unzipped the torrent file with Archive Utility. It give me the sims.app and I drag it into the applications folder. However, when I click it to run it/install it...nothing happens   . I have waited 15 minutes. Mind you I installed a similar torrent yesterday afternoon and it worked fine but I had to uninstall/delete that torrent for bug issues. Now when I use you all's or anyone else torrent it just will not open. Actually, (since this is a MAC os forum) normally when you open an app in Mac the icon bounces to let you know that "hey I'm getting ready to applicate" the sims app doesn't even do that and I'm really at a lost.
