I have the same problem.I was unable to open Windows Live Mail. A message came up that I needed to update to Windows Live Essential. I did this and Windows Live Mail opens and receives emails but |I am unable to reply to any or to create new emails. The system just gives me a huge page of 'computer gobble de guke' containing several error messages. I have tried System Restore to go back to where I used to be and then it wont let me open Windows Live Mail again. If I uninstall Windows Live Essentials will the system go back to where it used to be with Windows Live Mail working again and will I keep all my emails and contacts or will I loose them all when I uninstall Windows Live Essentials.
