Connecting windows live Mail on a laptop

I am trying to connect email on a laptop to the same email address which is working happily on a desktop PCs. Both computers are using windows 7 home premium. The windows live mail id is connected to a btconnect.com address and as I say works happily on the desktop pc. I have used exactly the same settings on the laptop as are on the pc without success. Any idea where I can be going wrong? After inputting the settings and trying to connect, I get the window up asking me to input the password, which ISO, over and over again.
