NodeWords upgrade has errors

I have tried to upgrade from both to the 2.0 alpha1 and the dev version of the version 1 of node words and got the following errors from version 6.x-1.11. I got some errors. Is it safe to continue to use the upgrade? I think it is working with minimal testing. The reason I am trying to upgrade is because I was hoping there would be something that would fix the performance problem I am experiencing about 30 milliseconds of database query time per node that is loaded on a page do to this module and it seems to add up.

The following updates are pending:

 nodewords module                   
 6168 - Implements hook_update_N(). 
 6169 - Implements hook_update_N(). 
 6170 - Implements hook_update_N(). 
 6173 - Implements hook_update_N().
