Crystal Reports : Access denied

Hi,

I have a Crystal Report that dynamically loads a report and passes on parameters. On our local network it works fine one different servers.
Now I've installed it on a clients server, and it doesn't work anymore.
This is the code I use:

VB Code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Try
            If Request.QueryString.Count > 1 Then
                'Declareren variabelen
                Dim i As Integer
                Dim pfFields As ParameterFields = New ParameterFields()
 
                'toevoegen parameters
                For i = 1 To Request.QueryString.Count - 1
                    AddParameter("@" & (Request.QueryString.Keys(i).ToUpper), Request.QueryString(i), pfFields)
                Next
 
                crvCrystalReport.ParameterFieldInfo = pfFields
                CrystalReportSource.ReportDocument.Load("C:\Inetpub\wwwroot\rapport\" & Request.QueryString(0))
                CrystalReportSource.ReportDocument.SetDatabaseLogon("sa", "password", "SERVER", "Database")
                
                crvCrystalReport.ReportSource = CrystalReportSource
 
            End If
        Catch ex As Exception
            Response.Write(ex.Message)
            Response.Write(ex.InnerException.ToString())
 
        End Try
 
 
 
    End Sub

AddParameter is a function that adds the paramater to the collection.

This works fine on our own servers.
Now I've placed it at the clients server, changed the login data, and now I get these errors:

Code:

Load report failed.System.Runtime.InteropServices.COMException (0x80004005): Access is denied. at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened()

Anyone know how to fix this?
