Error in rescheduling a report programatically

Question

Hi All,
I am trying to reschedule a report to use a new password using a c# program. But when I run the new schedule, the instance always shows "running" status. If I click on the status, I get the message "An error has occurred: The property with ID SI_NAME does not exist in the object" .  Please find below the code snippet. Am I missing something?
IDE: VS 2005
Server : CRS 2008 V1
BOE SDK Version: 12.0.1100.0
What I am trying to do is
1. Find the recurring schedules in the Crystal Server
2. Load their parent reports
3. Reschedule the parent reports
4. Delete the old recurring schedule
Is there any other way to update the properties (like db password) on a recurring schedule?
=======================================================================
SessionMgr sessionMgr = new SessionMgr();
EnterpriseSession entSession = sessionMgr.Logon(lUid, lPwd, lServer, lAuth);
EnterpriseService entService = entSession.GetService("InfoStore");
InfoStore infoStore = new InfoStore(entService);
string query = "select SI_ID, SI_NAME, SI_PARENTID from ci_infoobjects where si_recurring = 1 and SI_NAME = 'TEST REPORT'";
InfoObjects infoObjs = infoStore.Query(query);
foreach (InfoObject infoObject in infoObjs)
    //Get the si_id for the parent report
    strParentID = infoObject.ParentID.ToString();
    //Load the parent report object
    string rptquery = "Select SI_NAME, SI_ID From CI_INFOOBJECTS Where SI_KIND='CrystalReport'And SI_ID =" + strParentID;
    InfoObjects infoObjects = infoStore.Query(rptquery);
    InfoObject infoObjectrpt = infoObjects[1];
    Report report = (Report)infoObjectrpt;
    SchedulingInfo schedulingInfo = report.SchedulingInfo;
    schedulingInfo.Type = CeScheduleType.ceScheduleTypeDaily;
    schedulingInfo.RightNow = false;
    ReportFormatOptions rfo = report.ReportFormatOptions;
    rfo.Format = CeReportFormat.ceFormatPDF;
    ReportPrinterOptions reportPrinterOptions = report.ReportPrinterOptions;
    reportPrinterOptions.Enabled = true;
    reportPrinterOptions.Copies = 1;
    reportPrinterOptions.FromPage = 1;
    reportPrinterOptions.ToPage = 1;
    infoStore.Schedule(infoObjects);
    //Delete existing schedule
    infoObject.DeleteNow();
    infoStore.Commit(infoObjects);
infoStore.Dispose();
infoObjs.Dispose();

Hi All,
Can someone help me with this please? I am not able to schedule a report using sdk. It does create an instance, but it fails with the error "Information is needed before this report can be processed.". The instance also shows around 15 parameters for a report that has only 5 parameters.  Any  help is highly appreciated.
Thanks
Ajith
