The Astute Graphics 12 month subscription provides full access to ALL plugins for 12 months and so, this method is only applicable if you are a legacy customer who hasn't yet moved to our subscription.
If you haven't yet moved to the subscription, you should have kept a record of your license keys for future use with the older Unified Installer installation method.
If you are experiencing any issues locating your license keys, please contact us quoting any known email addresses to which your plugin(s) are currently registered.
