Why is it that I'm only permitted to use a fraction of the export types that are obviously available to me? Take note of the following code:

Dim crxApp As new CRAXDDRT.Application()
Dim crxRpt As CRAXDDRT.Report

crxRpt = crxApp.OpenReport("D:\MyReport\HANSCOM-PHReBills.rpt")
        With crxRpt.ExportOptions

            '.FormatType = CRExportFormatType.crEFTText
            .FormatType = CRExportFormatType.crEFTRichText



            .DiskFileName = "D:\MyReport\Exports\MyExport.rtf"
        End With

        crxRpt.Export(False)

It works if I use crEFTRichText but I get the following error if I use crEFTText.

If I alter crxRpt.Export(False) to crxRpt.Export() the system will prompt me with export options and my suspicions are confirmed that my options are very limited. But I can tell from the code in the application that I've inherited, it has not always been this way. This used to export using crEFTText (as CSV). Now I can't do that. Please advise.

Note: I'm using craxddrt.dll version 10.5.0.1943 on Visual Studios 2008.
