Error exporting to xlsx from SSRS 2008 R2

I have aspose cells 1.7.0.0 on sql server 2008 R2 and windows server 2008 R2. All of my reports export fine. However, one report yields the following error. SEE ATTCHED EXCEL OUTPUT FILE.

Note that it exports perfectly to the XLS native export that comes with ssrs 2008 R2. I tried aspose xls and it blew up as well.

Hi,

Please try the latest version: Aspose.Cells for ReportingServices v1.8.0.1 (SSRS 2008R2)

If you still face the issues, please post your report define (RDL) file here.

We will check it soon.
