Hi, I have a number of pptx files which failed to open with this exception
Aspose.Slides.Pptx.PptxException: reading animation group failed. —> System.NullReferenceException: Object reference not set to an instance of an object.
Opening files were done the usual way using PresentationEx constructor. I have attached a sample presentation. Thank you very much.
