How to troubleshoot Crystal Errors

Question

Hi,
I am hoping someone can help me.  We print Crystal Reports through a third part application.  We have Crystal 2008 developers edition installed.  Things will be fine and after about the 10th job we receive the following error: 
Exception:CrystalDecisions.Shared.CrystalReportsException
Message:Load report failed.
Source:CrystalDecisions.CrystalReports.Engine
Target:Void EnsureDocumentIsOpened()
Stack trace:   at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened()
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename, OpenReportMethod openMethod, Int16 parentJob)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename)
   at Accellos.Integration.IntegrationServer.InitReport(String reportId, String reportFileName, PlatformDataProviderConnectionInfo conInfo, IEnumerable`1 tables, IEnumerable`1 parameters)
Inner Exception:System.Runtime.InteropServices.COMException
Message:Unknown error 0x80040200

Hi Ludek,
I want to thank you very much for your replies.
Please note I have been working with the developer on this and we have not been able to determine the cause.
It also is worth noting that this is not reproducable on their TEST BOX with the same code.
On their Production Box it works, then stops, we re-submit and it works again.  I dont know if you are able to review what I have pasted here but here is a snippet of the code.  We have been troubleshooting this for 3 weeks now so any thing you can advice would help.  Also, does SAP have a Pay per Use support?  If they do,  are the support reps at a level that they could help us to debug what is going wrong?
