Dear Amit H,
Glad to hear that the version works well.
Your license expired on 2017/1/18, our versions released before this date are available for your license. And the version Spire.Pdf 3.8.121 I provided is the latest version before the date, that is to say your license is valid for the version 3.8.121, so please be assured to use it to deploy your application.
Sincerely,
Nina
