My father's Windows Live Mail has been working just fine until an update was installed two nights ago.  Now, it will not open.  No error, nothing.  The circle just spins and spins and nothing happens.  I have tried seeing if there are other updates, and there are not, making sure he has the latest version, and he does.  I have done the "repair" option twice.  Still.... nothing.  He is operating on Windows 7.  His computer has sufficient space.  I went through to troubleshoot anything and everything possible, spending 7.5 hours on his computer last night.  We worked offline, online, turned off his antivirus, made sure he had no malware on his computer - literally everything I could think of.  It just will not open.  He needs his old emails, so I am not brave enough to uninstall it completely because he will lose everything.  Without being able to open it to export contacts, email, addresses, calendars, etc.... we are stuck.  Please help!  (He does not have a Windows Live login, either.)
