Error when viewing report.

Hi.

I got eror when I viewing new reports.

The db connection test is ok.

Got this errormessage:
DotNetNuke.Services.Exceptions.ModuleLoadException: Failed to load database information. Error in File Task overview {A5B2D7CC-54C1-46AF-96C0-6A3DF29A3011}.rpt: Failed to load database information. ---> System.Runtime.InteropServices.COMException: Failed to load database information. Error in File Task overview {A5B2D7CC-54C1-46AF-96C0-6A3DF29A3011}.rpt: Failed to load database information. at CrystalDecisions.ReportAppServer.Controllers.DatabaseControllerClass.SetTableLocation(ISCRTable CurTable, ISCRTable NewTable) at CrystalDecisions.CrystalReports.Engine.Table.set_Location(String value) at Aricie.DNN.Modules.CrystalReportViewer.CRDisplayReport.ApplyLoginInfo(ReportDocument _oRpt, TypeConnection typeConnection, String dsnFilePath) at Aricie.DNN.Modules.CrystalReportViewer.ReportViewer.LoadCrystalReport() at Aricie.DNN.Modules.CrystalReportViewer.ReportViewer.Page_Init(Object sender, EventArgs e) --- End of inner exception stack trace ---

I have develope one report on the locale environment and one is moved from my local computer.
Both is running on my server.

What can I do to fix this?
