Custom assembly problems in RS

Hi,
I have a custom assembly that is working just fine in the Preview tab in Report Designer. However, the popup preview is blowing up with the error: Execute permissions cannot be acquired.
I've added a code group (at the top of the code group section) in the rsPreviewPolicy.config, which is residing in the default location. My .dll is in the correct place and functioning, as evidenced by the preview tab success. The .dll is using ADO.net to call a stored proc in an Oracle database.
I added the code group by directly editing the config file; I'm no XML veteran, so I'm not sure if it's configured correctly. The .Net editor tells me it's "well-formed". When it wasn't well-formed, I got an error regarding loading the file, so I'm assuming this isn't the problem.
Any insight would be appreciated.
Doug

Unless you assert the permission explicitly in the custom assembly code, it
will fail with a security exception.
Example for opening a connection to a SQL Server:
...
SqlClientPermission permission = new
SqlClientPermission(PermissionState.Unrestricted);
try
{
permission.Assert(); // Assert security permission!
SqlConnection con = new SqlConnection("...");
con.Open();
...
}
