How do I renew my licenses key of oracle dotconnect because I am facing the following error.

Error :

LicenseException: Feature is not supported. This error is thrown by Devart .NET Standard assemblies if license key validation fails. Possible reasons: 1. License key is not found, refer to the "Licensing .NET Standard (.NET Core) Projects" article in the product documentation. 2. Your product edition (the key was generated for) doesn't support the feature you are trying to use, refer to the editions matrix. 3. Your key is outdated for using the current product version, renew the license key in the Customer Portal.
