Report Load Error

Question

After running 30-40 Crystal Reports we get a 'Report Load' error on the .Load() command. At this point we cannot run any of our 8 reports created with Crystal Reports. To resolve the issue we restart IIS and then the reports load and run without problem.
Recently we upgraded our project from .NET 1.1x, VS2003, CR 9.X  to  .NET 2.0, VS2005, CR 10.2. This intranet web site runs under IIS 6 on WS 2003. Prior to the upgrade we did not see this behavior.
To create the report we send Crystal Rerports a dataset and then output the report to a PDF. Any ideas on how we can resolve this issue?
Here is sample code for producing our reports:
<code>
                   Dim amortReportDocument As ReportDocument
                   Dim reportPath As String = Server.MapPath("./amort.rpt")
                    amortReportDocument = New ReportDocument
                    amortReportDocument.Load(reportPath)
                    amortReportDocument.SetDataSource(ds1)
                    Dim myExportOptions As CrystalDecisions.Shared.ExportOptions
                    Dim myDiskFileDestinationOptions As                                                                           CrystalDecisions.Shared.DiskFileDestinationOptions
                    Dim myExportFile As String = FilePath & FileStamp & ".pdf"
                    myDiskFileDestinationOptions = New CrystalDecisions.Shared.DiskFileDestinationOptions
                    myDiskFileDestinationOptions.DiskFileName = myExportFile
                    myExportOptions = amortReportDocument.ExportOptions                    myExportOptions.DestinationOptions = myDiskFileDestinationOptions
                    myExportOptions.ExportDestinationType = ExportDestinationType.DiskFile
                    myExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat
                    amortReportDocument.Export()
                    Response.ClearContent()
                    Response.ClearHeaders()
                    Response.ContentType = "application/pdf"
                    Response.WriteFile(myExportFile)
                    Response.Flush()
                    Response.Close()
                    Response.End()
                    amortReportDocument.Close()
                    amortReportDocument.Dispose()
We added the following to the page unload event:
    Private Sub page_unload(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Unload
        GC.Collect()
    End Sub
</code>

Ok lets try this:
Right click on the temp folder (where the .rpt filed are getting created at runtime) -> properties.
go to Security tab.
click on Add.
enter (with out "") "IIS_WPG" in Object name window.
Click on Locations.
Select the machine name in the tree.
Ok.
Click on "Check names".
OK.
Give full control to it. (For testing purpose please ignore any warning signs).
OK.
Also please include the ReportDocumentObject.Close(), ReportDocumentObject.Dispose() and GC.Collect() in your page_upload event.
Does it help?
