When you make a purchase in the gold store, the payment window opens in a new tab or window (see video at bottom of page). If it window does not appear, the reason might be your browser blocking pop-ups.
An error or icon may show in the browser bar, click it to find more options and allow the pop-ups.
If the icon does not show follow the detailed instructions for all major browsers:
