ArgumentOutOfRangeException when opening workbook

I have a spreadsheet that can't be opened by Aspose.Cells ( The code looks like this:

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();


I get ArgumentOutOfRangeException. Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: startIndex

Here is the call stack:
