Enterprise Library (June 2005) Exception Handling Policy Error

Enterprise Library (June 2005) Exception Handling Policy Error
We have connected our middle tier components (from a asp.net front end) to 
our new SharePoint controls and cannot figure out why we keep getting a 
Policy Exception. We have modified the Enterprise Library code to use a 
centralized configuration file (so we don't need them in each web part) using 
this http://weblog.gpconsulting.com/archive/2005/06/23/159.aspx as a guide, 
even though it is for the newer EL. Any recommendations on what we're missing 
here as everything was working fine when we had added our policies 
(configuration) to the web.config file for our ASP.NET application. We didn't 
put any EL Exception code  inside the Web Parts (they just rethrow exceptions)

"System.IO.FileNotFoundException: File or assembly name
