asp.net report (rdlc) file cannot create dataSource

With asp.net 2005 - after I create a report (rdlc) file, I try to create a
Data Source (Report menu, then click "Data Sources", I get error:
The root element of a WC3 XML Schema should be <schema> and its namespace
should be 'http://www.w3.org/2001/XMLSchema'.
Can I fix this?
Thanks

JayYou can create the data source later in the ReportingServe Manager.
Dont use shared data sources in this case..
I dont know why you are getting that error but that is an alternative.
