Windows 7: Windows Live Mail issues

I know that my account has/was setup correctly but when I came back to my laptop some several hours later I was unable to send/receive and this is the response I get.
===============================================================
Unable to send or receive messages for the Optusnet.com (masaloi) (2) account. An incorrect password was entered. The next time you send or receive messages, you'll be asked to enter your user name and password for this account.
Server Error: 0x800CCC90
Server Response: -ERR Login failed.
Server: 'mail.optusnet.com.au'
Windows Live Mail Error ID: 0x800CCC92
Protocol: POP3
Port: 110
Secure(SSL): No
==============================================================
I am able to use the internet.
I have done a repair of Windows Live essentials hoping that would help but no way.

All assistance appreciated
thanking you

Have you got two accounts with the same name? Perhaps that's related to the issue.

Problem solved.
Issue was with server.
