Email using Windows Live Mail worked earlier today.  Now, we receive a message that says:

Unable to send or receive messages for the Centurytel (carolstallings) 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 internal server error
Server: 'mail.so.centurytel.net'
Windows Live Mail Error ID: 0x800CCC92
Protocol: POP3
Port: 110
Secure(SSL): No

We have reentered the password several times and continue to get the message at the point it is authorizing, so it will not download any messages.  I'm a novice at this.  What can I do?
