An item with the same key has already been added
posted

I'm using Infragistics.Excel.v8.2 (8.2.20082.1000).  I am attempting to open an excel file using the " Workbook.Load" method.  However, as soon as I open the file, I receive an exception

"An item with the same key has already been added"

I'm not sure why this error is occurring or why it is happening.  Any help would be greatly appreciated.  I have attached a zip file that contains the spreadsheet.

Thanks

    I thought I would put the stack trace here too (I removed the last line).
