Hi Kamalika,

Please download and try to use the latest version of Aspose.Pdf.Kit. You can download Aspose.Pdf.Kit for .NET 3.5.0.0 from this [link](http://www.aspose.com/community/files/51/file-format-components/aspose.pdf.kit-for-.net-and-java/default.aspx).

I’m sure, it’ll resolve your issue. However, if problem persists then please share the PDF file you’re having problem with.

We’re sorry for the inconvenience.
