My Sims Kingdom Wont extract

I've downloaded the file several countless times, but it still wont extract, I've tried Flashget and normal download and it still won't extract.I'm using Windows vistaWinrar V 3.70

Where did you download this? We don't have it on our site so it must have either been elsewhere or my post in the trade section.If it's mine then you need to make sure you have the latest version of winrar.
