On my end they show as "sent" but when I try to see them, they are not there. This computer is one day old so is it at my end or not? Any idea what I could do to make it work?
What browser are you using when this happens? If it's Internet Explorer, that might be the cause. That browser is just horrible, and full of bugs that are impossible to work around.
All internet users should use a modern browser like Chrome or Firefox.
