I have Windows Live Mail on a Windows 8.1 computer that suddenly won't send or receive.  The actual error message follows

Unable to send or receive messages for the Sbcglobal (rpnic3) account. The email server returned an error.

Server Error: 0x800CCC90
Server Response: -ERR Cannot connect to POP server 98.138.12.111 (98.138.12.111:110), NB connect error 1460
Server: 'pop.sbcglobal.yahoo.com'
Windows Live Mail Error ID: 0x800CCC90
Protocol: POP3

My web mail works fine. My other computer with Windows Live Mail also works fine. Settings on both computers appear the same. I removed and added my email account to no avail.
Thanks for your help
