I am receiving these errors after I installed Ubercart for Drupal 6

The only forum I was able to find that was related was
http://drupal.org/node/384652

Which recommends adding a patch to convert the Workflow_ng table to ca_predicates
This forum was closed in April 2009.
I do not know if this patch was already implemented into the upgrade or not. And if not, I need advice on how to add this patch to my code. Or, more basically, how do I fix these errors?
thank you
