I cannot send/receive emails today. I'm just getting this error message;

Unable to send or receive messages for the Jcpolishing.co (joncarter) account. The host 'mail.jcpolishing.co.uk' could not be found. Please verify that you have entered the server name correctly.

Server: 'mail.jcpolishing.co.uk'
Windows Live Mail Error ID: 0x800CCC0D
Protocol: POP3
Port: 110
Secure(SSL): No
Socket Error: 11004

Any ideas??? I'm assuming from this message the problem is not at my end but I cannot seem to find anyone to contact about this to get it fixed.
