This error is dependent on which viewer you have chosen to view reports in your CE9 installation.
If you have chosen the Dynamic HTML viewer the service that is processing the report is the RAS - the Report Application Server. If you have chosen any other viewer, the report is being processed by the Page Server.
If it is the RAS then you need to:
1. Go to Start > Programs > Crystal Enterprise 9 > Crystal Configuration Manager.
2. Click 'Crystal Report Application Server' and then click the 'Stop' button.
3. Right-click 'Crystal Report Application Server', and then click 'Properties'. The 'Crystal Report Application Server Properties' dialog box appears.
4. On the 'Parameters' tab, in the 'Option Type' list, click 'Database'.
5. Under 'Max Number of Records', click 'Unlimited', and then click 'OK'.
6. Restart the 'Crystal Report Application Server' service.
After completing these steps, you are now able to successfully preview the report.
If you have chosen a different Viewer, then do the same for the Page Server.
