From one day to an other all of sudden I couldn't download my emails on Windows live mail. I use Comcast connection and my server is from Italy.

Every time I open the Windows live mail this appears:

Unable to send or receive messages for the Libero (....[my name]...) 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 [AUTH] POP3 access not allowed
Server: 'popmail.libero.it'
Windows Live Mail Error ID: 0x800CCC92
Protocol: POP3
Port: 110
Secure(SSL): No

I know the account name and password are correct, so what's the problem?
