Not able to receive emails at Windows Live Mail

I have not had any problems so far until the last one week when I could not get my emails to appear on my Windows Live Mail.  I get this message:

Unable to send or receive messages for the robmei2001 account. Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.

Server: 'pop.mail.yahoo.com.sg'

Windows Live Mail Error ID: 0x800CCC0F

Protocol: POP3

Port: 995

Secure(SSL): Yes

I checked all my configurations accordingly and everything is correct.  But still cannot get emails.  Can someone please help me?

Thanks
