You should continue to use the existing version of SADiE and additional downloads that you have installed. The Free version is not a direct upgrade or replacement for fully licensed SADiE 6 systems and should be treated as a separate, license free edition.

The free release is intended only for use on new computers that do not rely on certain legacy features or older, discontinued hardware. Support for key functionalities, such as CEDAR plugins and CD burning and reading has been removed (though DDP writing is still available). The bundled iZotope tools are no longer included in this version.

Additionally, while the FREE version remains compatible with BB2, BB2J, and LRX2 hardware, this should be approached with caution and only on a fresh system to avoid overwriting any existing licensed installation. This release does not support older SADiE hardware such as PCM4, PCM8, H8, H16, or H64.
