Windows Live Mail — Cannot add Comcast Email account

I am trying to add my comcast email account to windows live mail, I already have another email account that properly downloads emails to windows live mail.

I go to Accounts then Email+ then I complete the pop up page to "add your email accounts".  I select manually configure settings and on next page manuallly complete ports, incoming, outgoing server, etc. as per comcast requirements.  When I click next, which should take me to the page to click on finish it just returns me to the (now blank) "add your email accounts" page.

I am running widows 8.1.

Please also note that prior to this issue I already had comcast emails on windows live mail, but every time I tried to receive emails, it required me to retype my password even though I have checked the "remember password" button.  So there seems to be some issue with remembering data put into windows live mail.

thanks
