We have a 64bits reporting server and SQL Server, and when I install the Enesys Data Extension tools, it installs on the 32 bits program files folder and I configured it according to the manual, copy Enesys RS Data exentsion dll to the SQL 2008 instance folder and  changed the rsreportserver.config and rssrvpolicy.config, but it doesn't work when I deployed a SQL 2008 report. get the following error:

• The report server cannot process the report. The data source connection information has been deleted. (rsInvalidDataSourceReference)

Any thing I did wrong? Before I deploy, it runs fine in my Visual Studio Designer.
