Functioning Windows Live Mail 2012 stopped sending and receiving messages for my MSN email account.  New mail and folders viewable and usable on outlook.com.

I have reviewed most questions regarding this issue on the community site and I have found no solution, so I need HELP.

My machine is running Windows 7 64-bit.  Computer protected by Microsoft Security Essentials.

On 5/9/2014 Microsoft SQL Server 2005 Compact Edition [ENU] (3.1.0000) was installed.  (I did NOT do this.)  I do not run SQL server and do not need it. I notice that SQL Server Compact 3.5 SP2 [ENU] and x64 [ENU] are present and installed 5/19/2011.  I may not need these unless they are needed by the system or other programs.  This may have been the cause or related to the issue.  No other recent program installation activity

Updates are current.  No update installed in the last few days when checked in Control panel.

I recently upgraded SQL 2005 to SQL 2008 R2 in order for a business program to operate properly.  However, since the upgrade, I am now unable to operate Windows Photo Gallery.  The error message indicates that Photo Gallery can't start because Microsoft SQL Server 2005 Compact Edition is missing.  It sends me to a link to install it, but if I install it, I fear that it will overwrite my version of SQL 2008 and I will lose the functionality of my business programs that require 2008.  How do I get Photo Gallery to work with SQL 2008?

 

Thanks for your help.
