Receiving "Object reference not set to an instance of an object." on LoadData()

Hi,

We have a program which is failing on the LoadData() call for a subset of our files (roughly 10%).
I've set up a test application which consists, literally, of :

try
{
Console.Write("opening workbook...");
Workbook wkbk = new Workbook();
wkbk.LoadData("broken_excel.xls");
Console.WriteLine("done");
}catch (Exception e)
{
Console.WriteLine("\n\ncaught: " + e.Message);
Console.WriteLine("\n\n\tat:" + e.StackTrace);
}
Console.ReadKey();


The exception is the following:

Object reference not set to an instance of an object.

The peculiar thing is that 100% of the models open correctly in Excel.

This is using Apose 4.9.0.0

What do you suggest?
