When I click on windows live mail it opens up then the calendar keeps updating and no email can be sent or received as it keeps flashing on updating calendar . Help

I have a new laptop that has two ways to get mail.  I can click on the mail envelope and that one works fine but does not have all the little icons I am used to so I then go to the app screen and type in windows live and it brings up my live mail hot mail account.  But it has stopped working.  It keeps flashing updating calendar and shows that unable to download mail screen.  Help
