I have been using windows live mail with my charter email account for 3 years and have had no problems. Now all of a sudden I cannot send emails, but I can still receive them. I get this error message:

The connection to the server has failed.

Subject 'test'
Server: 'SMTP.charter.net'
Windows Live Mail Error ID: 0x800CCC0E
Protocol: SMTP
Port: 25
Secure(SSL): No
Socket Error: 10060

Does anyone have any idea how to fix this/

Thanks.
