When Performing LiveUpdate "NIS Engine Failed to Complete" on NIS 2012 Ver 19.6.1.8

I have latest version of NIS 2012 (19.6.1.8) as of Mar 31st and received the above mentioned msg when performing a manual LiveUpdate.

 

I initially had a "8504, 101" error that NIS self-corrected.

 

Have tried several manual update attempts and restarts and continue to get msg.  

 

Please HELP!!!!
