The short answer is that they are unavailable.
We have phased out Circle(1) completely and urged users to stay up to date with the latest releases.
💡 If you have purchased a license of Circle(1) you are entitled to a free upgrade to Circle². You can download the latest installers here and use your original activation code. If you run into any issues, please contact FAW Support and we'll help you out.
💡 Presets are forwards compatible. You can still use your old Circle(1) presets in Circle². The presets can be moved manually by moving the Presets Folder from the Circle(1) program files into your Circle² program files.
