I just upgraded to NetAdvantage 11.2. In my application, I am trying to import a workbook with user defined functions. When I call the function WorkBook.Load(fileName), It crashes with an ArgumentNullException. The formula string cannot be null. Parameter name: value. The stack trace says it occurs at:

   at Infragistics.Documents.Excel.Formula.TryParse(String value, CellReferenceMode cellReferenceMode, FormulaType type, WorkbookFormat fileFormat, CultureInfo culture, Formula& formula, FormulaParseException& exception)
   at Infragistics.Documents.Excel.Formula.Parse(String value, CellReferenceMode cellReferenceMode, FormulaType type, WorkbookFormat fileFormat, CultureInfo culture)

Is there something I am doing wrong that could cause this to happen? Is there a way to prevent it from happening?

I do not need to save the formulas. I just would like to be able to grab the values from cells without the functions.

It occurs on the first line of my import method: var wb = WorkBook.Load(fileName);

The file, in my case, is fairly database dependent, so if an example is needed I will try to come up with something.

Thanks In Advance
