Windows Live on Microsoft 10

I downloaded Windows Live on my new laptop with  Windows 10 on it.  It loaded ok and opens, but a box keeps popping up asking for the user name and password although the button on the right side of the panel sometimes says it is signed in.  The box has the information filled in (although I am not sure of the password being accurate), and it pops up again every time I enter it.  A box occasionally comes up when I open the program that says, "To help protect your information, please sign in again".  No matter what I have done, I have received and sent no mail.  Is the password the newwavecomm.net password or some other one?  I use the name before the @ sign for the name.  Thanks!
