Since yesterday I am unable to send or receive Gmail in Windows Live Mail.  All my other 3rd party accounts work just fine, only my Gmail accounts are affected, and here's the message I get:

Unable to send or receive messages for the *** Email address is removed for privacy *** account. Header download for the 'Inbox' folder did not complete. Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.

Server Response: Your IMAP command could not be sent to the server, due to non-network errors. This could, for example, indicate a lack of memory on your system.
Server: 'imap.gmail.com'
Windows Live Mail Error ID: 0x800CCC0E
Protocol: IMAP
Port: 993
Secure(SSL): Yes

I changed ports, that didn't work.  I tried Gmail's server suggestion:  imap-mail.gmail.com but that didn't work.  I even deleted one of my Gmail accounts from Windows Live Mail hoping once I added it back, all would be resolved, but that didn't work either.

Running Windows Live Mail 2011 Build 15.4.3555.0308 on Windows 7

Any help would be most appreciated.
