Re: sims 3 store content: I "do not own the item"
@rinandia When you see this error, does it help to simply refresh the browser page? You can try downloading from the items' individual product pages rather than your purchase history so you're not refreshing the entire history.
If that doesn't help, try using a different browser.
If that doesn't help either, please list at least a few of the items that won't download properly.
