Crystal Reports 2008 SP3 &VS Studio 2008

Question

Hi,
i'm trying to use Crystal Reports 2008 with SP3, Visual Studio 2008 and OS Windows Server 2003 (I use this Server OS because i'm developing for Microsoft SharePoint).
Before upgrading to Crystal Reports SP3 i could not set a basic Visual Studio C# Dataset as the Datasource of my Report. Everytime i get the following Error:
Unknown Database Connector Error - Error in file temp_GUID.rpt
Then i read theis forum and it was mentioned that maybe SP3 could solve this problem. But after applying CR 2008 SP3 the following Error occur (VS cancel the debug mode and this error is logged to the Windows Server-Log):
Message: Could not load file or assembly 'crdb_adoplus, Version=12.0.1100.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418)
I'm using the following Code-Snippet:
CrystalReport1 report = new CrystalReport1();
NewsDataSet nds = new NewsDataSet();
DataRow r;
r = nds.Tables[0].NewRow();
r["Title"] = "Title";
r["Body"] = "Body";
nds.Tables[0].Rows.Add(r);
//Now the exception will be thrown
report.SetDataSource(nds.Tables[0]);
Maybe someone can help me to solve this problem.
Thanks in Advance!

Well guys,
i spent the whole day with installing and uninstalling the CR2008 Service Packs with no success. My opion was that eventually the " CR2008 SP3 Full Build" from this download site
https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/bobj_download/main.htm
causes the error, but after applying SP1 the same error occurs.
As a reminder the error text:
Message: Could not load file or assembly 'crdb_adoplus, Version=12.0.1100.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418)
or
Exception: System.UnauthorizedAccessException
Message: Access to the path 'C:\WINDOWS\TEMP\temp_51231be7-4c43-40f1-b0ee-67e76414e046.rpt' is denied.
StackTrace:    at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.IO.File.Delete(String path)
   at CrystalDecisions.CrystalReports.Engine.ReportClass.Dispose(Boolean bDisposeManaged)
   at CrystalDecisions.CrystalReports.Engine.ReportClass.Finalize()
Maybe its a permission problem, but the ServiceAccount which performs the action has full control on the temp and CrystalReports Installation folder, so i don't know what to do else.
Then i tried to  resolve the error, which occurs without any Service Pack:
Unknown Database Connector Error
Error in File temp_184c79e9-4eeb-41dd-9043-582b30ac7281 {82AF1B98-C271-4007-B793-723CCFD63FFD}.rpt:
Unknown Database Connector Error
Also with no success. I'm using the following Code-Snippets:
Simple XML-Schema (xsd) because i don't use a Database and the data is generated dynamically:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="NewsSchema"
    targetNamespace="http://tempuri.org/NewsSchema.xsd"
    elementFormDefault="qualified"
    xmlns="http://tempuri.org/NewsSchema.xsd"
    xmlns:b="http://schemas.microsoft.com/BizTalk/2003"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
  <xs:element name="News">
    <xs:complexType>
     <xs:sequence>
        <xs:element name="Title" type="xs:string" />
        <xs:element name="Body" type="xs:string" />
      </xs:sequence>
    </xs:complexType>
</xs:element>
</xs:schema>
Then i add this as an ADO.NET (XML) connection an i'm able to integrated the two fields in the report.
Then i try to call the report with the following C#.Net Code:
+DataSet ds = new DataSet();
DataTable t = new DataTable("News");
+DataColumn title = new DataColumn("Title");+
+DataColumn body = new DataColumn("Body");+
+title.DataType = Type.GetType("System.String");+
+body.DataType = Type.GetType("System.String");+
+t.Columns.Add(title);+
+t.Columns.Add(body);+
+ds.Tables.Add(t);+
+DataRow drDataRow;+
+drDataRow = t.NewRow();+
+drDataRow["Title"] = "My Title";+
+drDataRow["Body"] = "My Body";+
+t.Rows.Add(drDataRow);+
//the exception is thrown here
report.SetDataSource(ds);
Now i'm really frustrated because i don't know what to do to resolve this problems and i stuck with this errors for a couple of days now. Any further help or suggestions would be great.
With kind regards,
Christian
