R – Crystal Reports

I upgraded my ASP.Net app from .NET 1.1 to .NET 2.0. All of the webpages still work fine, but the Crystal Reports won't load.

Stack trace:

Load report failed.
StackTrace:    at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened()
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename, OpenReportMethod openMethod, Int16 parentJob)
   at CrystalDecisions.CrystalReports.Engine.ReportClass.Load(String reportName, OpenReportMethod openMethod, Int16 parentJob)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.EnsureLoadReport()
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSource(DataSet dataSet)

Does anyone know why it won't load?

Architecture: Windows Server 2008 (IIS 7)

Code to call report:

ReportClass ApprovalPage=new CustomerJobLabelApprovalMod();
ApprovalPage.SetDataSource(reportDataSet);

Code for CustomerJobLabelApprovalMod:
