Write report on SQL Stored Proc

[swhitten]

Crystal XI. SQL 2005. I am trying to write a new report off a SQL Stored Procedure. Wen I try to add the data to the report, it prompts me for all the various paramters for the stored proc. I click "set as null" for each, then click ok. Then I get this error:

Database Connector Error: 'Cannot obtain error message from server.'

I am connected as sa, so this should not be a rights issue. Any other ideas? Thanks!
