If you had the SSL Native Essentials pack that included the original Channel Strip and Bus Compressor licences then you may have noticed that these are labelled SSL Native Channel strip 2 and Bus Compressor 2 within iLok.
Your licenses are not lost, they are rebranded to current production software:
They will continue to work with the original Channel Strip and Bus Compressor.
The original licenses also enable the V2 versions; to use V2, simply download and install the V2 version.
If you do not see version 2 in your iLok, it is most likely because you need to update your iLok License Manager.
