Needed to completely restore my system with the disk for Windows 7, performed all the updates,  and after reconnecting to Windows Live Mail (all accounts properly installed)  I received a small warning about something not working properly due to a missing .dll.  I attempted to find it doing some research, and eventually had to ignore it as cleaning the registry found nothing wrong or missing. 

Then I found a problem with using POP port for Comcast,  which told me to chang to their IMAP setting,  which I did,  but it has not solved my constant warning popups of " server has unexpectedly terminated service...

code 800ccc0F"  and today it is 800cccde.

I am using WLM 12  to receive my Comcast and Gmail  accounts. The problem seems to be with Comcast,  though they insist it lies with Windows Live Mail.   My IE is version 11,  though I don't see where that is involved.

Looking through answers already existing has not helped my problem,  so I'm hoping someone can solve it before I lose my mind!  The warning comes up every few minutes,  sometimes seconds!  It does not always really disconnect me from the internet,  but most often affects sending mail.  And yes,  I have check the Ports innumerable times and they 're correct.
