Re: Sims 3 Aurora Skies World Not Installing

@racheyisabean  Try using a different browser: Firefox and Internet Explorer work better with the store than Safari or Chrome.

If that doesn't help, try downloading the world into a clean user folder.  Move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop, open the launcher to spawn a clean folder, and then try to download just AS, nothing else at the same time.  Let me know whether it works.
