Форум поддержки Thunderbird

My hard drive had to be replaced and now I cannot recover my Thunderbird Email. Keeps asking for a password but won't accept it. Asks for password for "mobile.charter.net" I think I have totally screwed up all the settings in trying to find a solution. I checked with my internet provider but no help. Could someone please help a very senior and very frustrated Granny? Thanks in advance.

This is in Thunderbird. I have a number of news feeds and they occasionally get stopped or paused. It's annoying. Is there a way to disable this paused account feature in Thunderbird? If I want an account paused, it should be my choice not Thunderbird's.
