It sounds like the report is being opened and showing the preview data that was saved withing the report as part of the support to act as a viewer for RPT files used to send report results in Crystals native format.
To save space, reports are normaly shipped with the preview data deleted vai a check box one of the config dialogs.
With that removed make sure that within IA all of the Tables and Input Parameters used bound to the Tables and Parameter definitions.
The "Report Parameter 'Date Range' is required but was not defined" error indicates that "Date Range" parameter from the report is not defined in the reprot configuration in IA, so IA does not know what to do with the parameter. Since we support Fixed (constant), System (supplied by report environment via definition, like current user), or User (supplied by user at runtime) attributes, the executor does not automaticaly turn the parameters into user input prompts.
