Windows Live Mail opens, but 'Authorizing' message remains.  If I click Send/Receive button I am prompted to enter user name and P/W.  User name is visible and P/W is series of dots.  Remember P/W box is ticked.  I I try ok, the prompt keeps reappearing, if I try cancel I see error message: Server Error 0x800CCC90, WLM Error ID 0x800CCC92.  Incorrect user name and P/W.  This problem started suddenly about two days ago.  I have tried changing my Microsoft Account P/W but that did not help.  I am not very computer literate and am now totally confused.  Any help appreciated.
