Enterprise Edition licenses do not auto-renew. In order to add or renew your current licenses, please place a new order at https://animbot.ca/home/buy-enterprise-edition/.
As usual, you will receive a keycode within 10 minutes of the purchase and will be able to generate your RLM license at animbot.ca/enterprise. You should install this new license and restart your RLM server. There's no need to delete the previous license, but you can do so if it has been expired.
For your convenience, you can place a renewal order with up to 30 days in advance of your current licenses expire date. For details please read the article How to set the license start date from Self Checkout
If you wish to add licenses that co-term with your current ones, please read this article:
