Hotmail error in Windows Live Mail

Does anyone know what's going on with this? I've seen plenty of threads about people being unable to access their Hotmail account through Live Mail, but there are very few responses. Should we assume that there is no fix? Is there one thread that addresses this?

"Unable to send or receive messages for the Hotmail (fiatdood) account. Sorry, we were unable to sign you in to Windows Live ID at this time. Please try again later.
Server Error: 0x80048820

Thanks
