Email account disappeared!

I was on Google and on Google changed a password and told them to interface with eMclient. I then went to my e-mail and my account has totally disappeared. All of the e-mails folders etc. I am overwhelmed as to what has happened. Hopefully this can be fixed as I have important information in that account

Okay my email account is back and working somehow the imap box was unchecked and I checked it and now it has appeared. However I am getting a message on my iPhone that the mail server imap.gmail.com is not responding?? Any help?
