If you renew your subscription before the expiration date, each new year in your subscription will be available at 50% off the new license price. The license period will be extended by one year from your subscription’s expiration date.
If your license expired less than 1 year ago, a renewed subscription will be extended for one year from the license’s previous expiration date. In this case, you will still receive 50% off the new license price.
If your license expired more than 1 year ago, your only option is to buy a new license. The renewed subscription will be valid for 1 year from the purchase date.
