I have Windows 7 64 bit, WLM 2012.

Tried control panel solution to repair Windows Essentials components- no changes, still does not receive or send.

Added another account - now I have two or three of everything and none of the accounts receive or send.

Tried unistall, reinstall WLM - no changes. still does not receive or send

Tried uninstall, reinstall Windows Essentials - no changes still does not receive or send

deleted duplicate account - still does not receive or send.

Deleted WLM account, then reinstalled WLM, and added my account again and now have two of everything, plus lost some folders and all contacts. 

I can send and receive on Hotmail on line, however the email folders will not sync between on line Outlook and WLM, nor will the contacts.

Did an "SFC /SCANNOW and no problems were found. 

when I click on ? in WLM, it brings me to Windows Movie Maker q and a on the web.

tried regedit solution given to similar problem (delete key "ssl.live.com_MBI_SSL) - there is no such key on my computer in "Computer\HKEY_CURRENT_USER\Software\Microsofwindows Live\Communications Cl9ients\Shared\Policies"

Did another system restore today and now have three of everything.

Please help.
