Access Creator Table

Access Creator Table

I am trying to define a workflow in CRM that needs to lookup a table (to get the approving manager).  I would like to use a simple lookup table in Creator which I would access from a deluge script in CRM.  But I have having trouble accessing the Creator table from the API - it returns "permission denied."  

I have a subscription to CRM but not to creator.  Will the free account work for what I want to do?
