Aspose.Diagram always throw exception when open an existed visio file

I download the example. But when I run the ExportPageToImage sample. It always throw an exception when execute the below code:

Diagram diagram = new Diagram(dataDir + “ExportPageToImage.vsd”);

The exception message is like below:
Error in element VisioDocument in \VisioDocument. Index was out of range. Must be non-negative and less than the size of the collection.

But it works when I open the visio file which created by myself.
