Can't Log In

Hello: My username and password are typed in at the top of the screen. It just won't connect to Comcast. It was fine until Comcast had a problem with their personal web pages. They said the only thing they could do was give me a new password. Beacuse this is third party software, they don't have anything to do with it. I read another post from someone who kept getting a dialog box that asked them to keep filling in their user name and password each time they tried to get in. The root admin. directed them to download a new build. I don't get this dialog box, but I was wondering if that download would work for me, too. Or is there something else I can do. Thank you.
