CalculateData throws error: Object reference not set to an instance of an object


I have attached a workbook with 2 sheets, the first sheet contains a pivot table and the second holds the data source. Using MS Excel 2010, I added a Calculated Field to the pivot table (2013 Price Growth Percent), then dragged it to the Values box of the pivot table using the Pivot Table Field List interface in Excel, then saved the workbook. I get the above object reference error when I subsequently open the workbook in Aspose. Please see attached workbook. Here is a simple test program you can run as a console app from Visual Studio:

static void Main(string[] args)
var wb = new Workbook(“OMPPBReportTemplate_2014120109584858.xlsx”);



Note that from within Excel the new calculated field works fine, so the formula appears to be well formed. I’m using Version 8.3.0 of Aspose.Cells.
