Wizard and custom Reports not rendering.

The out of the box reports run correctly, but the custom reports and reports created with the report wizard do not display.  

The report log shows the below error ( I apologize for adding the stack).  I've followed various threads to set the spns.  The same error is thrown after the spn change.
