The connection to the server has failed.
Subject 'survey form updated, n still in progress...'
Windows Live Mail Error ID: 0x800CCC0E
Socket Error: 10060
and a little bit about why is this happen. after i moved house, and try to connect with new internet connection, my vista couldn't connect to the wifi until i change the registry number.
and after that this problem occured as well.
i hope you guys can help me with this problem, thank you in advance.
