Getting error while reading fbx file

Hi Team,
I am using Aspose.3D in our project for converting 3d files to obj format. Sometimes it gives error “Cannot open this file”. I am using following code to read file.
Scene scene = new Scene();
scene.Open(file.OpenReadStream());
scene.Save(dstStream, Aspose.ThreeD.FileFormat.WavefrontOBJ);
Please resolve my problem. I am uploading that file
