Windows Live Mail

In the last couple of days my Live Mail tries to receive my email from Shaw but gets "stuck".  Nothing happens.  I have notification an update is available.  I give permission for Windows to access my computer to install update.  Nothing happens.  I have tried to repair Windows Live Mail .  Informed repair successful.  Problem continues.  I have Windows 8.1   Now I can't do a normal shut down as the Windows Live App is still running so I just "shut down anyway"  This is a real aggravation as the mail app that comes with Windows 8.1 is incompatible with Shaw for displaying attachments and now I can't get email at all unless I use Web Mail
