Aspose Total Older Version Download Link

I got error when applying Aspose.Words for .NET version 20.9.0.0 SetLicence(“Aspose.Total.lic”) in winform application. Aspose.Total.lic is set as embedded resource. I downloaded Aspose.Total library through Nuget v.20.9.0. Can you provide links to download older version before March 29, 2018?
If not, can you provide a quote to upgrade new subscription?

The subscription included in this license allows free upgrades until 29 Mar 2018, but this version of the product was released on 01 Sep 2020. Please renew the subscription or use a previous version of the product.

@tduong,
Your license is valid for using Aspose.Words for .NET 18.3 and all the versions released before this version. You may download the NuGet package for this version from the following link:
