CRVS2010 Beta - Crystal Report Problem

Hello, I am using Visual Studio 2010 and Crystal Reports(beta) for VS2010. The problem i am having is that if i populate the Report from a DataSet or a DataTable, The Application Throws an Exception "An unhandled exception has occurred in your [SolutionName].vshost.exe.

The Exception is shown only when i close the application

This exception is shown only in Debug Mode.

If i run the application and dont open any crystal report then every thing works fine.

IMP!!!!!!!!!!Moreover this Exception does not occur if i populate my Report directly from a 'Stored Procedure' in DataBase.
