Error on Exporting Matrix to Excel

I get the following error when deploying my matrix to excel:
Reporting Services Error
----
Exception of type Microsoft.ReportingServices.ReportRendering.ReportRenderingException was thrown. (rrRenderingError) Get Online Help
Exception of type Microsoft.ReportingServices.ReportRendering.ReportRenderingException was thrown.
Object reference not set to an instance of an object.

I was previously able to export(prior to SP1). Any thoughts?
Thanks,
ShaneCan you post the RDL? Can you view source on the error page and see the
stack trace?
