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


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 :

Console.Write("opening workbook...");
Workbook wkbk = new Workbook();
}catch (Exception e)
Console.WriteLine("\n\ncaught: " + e.Message);
Console.WriteLine("\n\n\tat:" + e.StackTrace);

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.
