After a year of working well in new computer, and following an automatic update of Essentials a few days ago, Live Mail freezes up right after opening. Have to reboot computer to shut it down.

Following suggestions in community, I have repaired Essentials several times, and done clean uninstall and reinstall. Occasionally, Live Mail works briefly, allowing download of new mail, but then freezes again. I'm tearing my hair out! Help!

The Skydrive client hangs at signin. The computer was built a year ago and Skydrive operated perfectly fine from the first day. This morning Skydrive came up offline and says "Skydrive - not signed in".

Computer - Desktop configuration, Windows 7 x64 with all updates running on Core i7-3770K, 16GB RAM, 2TB HDD

Steps taken so far:
Reboot computer - multiple times
Reboot Internet router, speed is 20/5
Exit and sign in Skydrive client
Uninstall and reinstall Skydrive client
Reset DNS to OpenDNS
Checked that IE is set to medium-high security

Everything but the Skydrive client is running nicely. I checked my laptop, which also runs Skydrive client to stay in sync with the desktop files, and the laptop is connecting without difficulty to the same files on Skydrive. The laptop is also Windows 7, but x86, 3MB RAM.

Thank you for your assistance.
