Yes. You can renew your license by registering a Support Renewal License. One Support Renewal License provides one additional year of support. By simply registering multiple Support Renewal licenses, you can bring your support period up to date. (e.g. If your support expired one and a half years ago, register two Support Renewal Licenses.) It is cheaper to get an extension with a Support Renewal license than purchasing another User License if you are within 4 years of the initial purchase.
