I haven't been able to receive mail from Windows Live Mail since May 2013.  It gives me the following errors:

Unable to send or receive messages for the Bellsouth (putt_l) account. 

Server Error: 0x800CCC90

Server Response: -ERR inactivity timeout

Server: 'pop.att.yahoo.com'

Windows Live Mail Error ID: 0x800420CD

Protocol: POP3

Port: 110

I have been searching this website for help and have tried several solutions, and so far I have only managed to now have to open my Windows Live Mail only if I run as administrator.  I can't seem to find this exact problem in any forum and really need some help with this.
