Email sub accounts not working

I use Windows Live Mail and have for years.  My main account works, but my sub accounts stopped working.  I get a pop up for my password.  It doesn't work and keeps popping up until I cancel and then I get an error that the email can't send or receive because the wrong password was entered.  This is the same password I've always used in the past.
