Windows Live Mail Error 0x80048820

If I'm lucky, I can get a connection once a day and get my mail to download. During that time, sometimes it will send my email responses and sometimes not. I sounds like a connection problem, maybe servers being down, but usually connection problems don't happen day after day after day. And like I said this has been going on for months. When I first switched to Live Mail (to get away from Hotmail Connector) it worked beautifully and I was very happy with it. So I don't know what has changed but now it is a frustrating nightmare.
