Window Essentials 2012 Problem

1.) Every time I try to send an email with a group address I have to go into Control Panel to repair the Windows Essential 2012.

2.) If I uninstall the Windows Essentials 2012 currently on my PC & then download Windows Essential 2012 from microsoft.com will I lose my Windows Live Mail & all the folders/messages/addresses?

3.) Why does updating Windows not also update Windows Essentials 2012 to eliminate this email problem?

Thank you.
