Size Limit of Result Set Exceeded in Advanced Analysis for Excel

I am getting a "Size Limit of Result Set Exceeded" error when performing a drill-down in Advanced Analysis for Excel. Is the limit 65,000 rows in Excel? I was able to get a drill-down of 39,000 rows to work, but failed when I exceeded 60,000 rows.

I am using Advanced Analysis for Excel v1 SP5 and Excel 2007.

Thanks.
