Error to export as an Excel format! Help!

[Mercury21]

Hi there,
I have a problem with Crystal Report 8.5 to export the report as an excel format file via ASP web application.

I am using the "rptserver.asp" to display and export the report on the client side web browser.
After I display the report preview, the error comes up when I clicked the export button and choose as Excel format.
(it's worked as rpt format and rtf format!)

The error message said "-2147190908: Failed to export the report."
I checked the code of the rptserver.asp; the error occurs at the line 485.

------------------------------------------------------
Response.binarywrite goPageGenerator.Export(8209)
------------------------------------------------------

The system is ASP 2.6 and MSDE2000 (The released version will be SQL Server 2000).
Platforms are Windows2000 Server/Professional and WindowsXP Professional.

I checked the Seagate Software web site and I tried to do as the web site said, but it was not working.

Please help me!
