Windows Live Mail 2012

We are using Live Mail 2012 and have Spectrum (old Time Warner/Roadrunner) email. I received an email today From: Google, Subject: Security Alert for your linked Google Account - which I cannot open. Not coincidentally, at the same time the email was received, I changed my GMail password on another email address, on another computer.  The Spectrum email address was set-up in GMail for secondary notifications. I now CANNOT open this one email (from Google) OR create a new email in Live Mail. I can receive email though.  I tried deleting the Google email in Live Mail and it doesn't take. I've called Spectrum, Google and Microsoft. The first two point fingers, Microsoft stopped servicing Live Mail in January. Any suggestions? Thank you, supportive public!
