After installing K2 blackpearl (SP1) and running the "K2 [blackpearl] Configuration Manager" for the first time, I get the following error message in a dialog box "SQL Report Service Site: Please make sure that your SQL Reporting Service webservice is running".  However, I believe that the webservice is running and I am able to browse to its URL (note, which runs on a non-default port) without any problem at...

   http://localhost:81/ReportServer/ReportService2005.asmx

What could be the problem?  Is it perhaps the non-standard HTTP port being used for the default website?  If so, where does one configure the webservice URL for the Configuration Manager?

Thanks.
