Most probable cause is something wrong with license key file, you need to do clean reactivation. So remove current keyfile and reactivate the plugin
"/Users/[your windows users name]/AppData/Roaming/D16 Group"
folder on your system drive
If you can't find AppData folder then click on the View tab (in the file explorer), above Show/hide check Hidden Items.
Once you do so, open DAW and try to reactivate the plugin, it should work fine.
~/Library/Application Support/D16 Group
'~' represents your macOS user branch, to get there you should with Finder as the active application, click on the Go on top menu, then holding the Shift key choose the Library
item and then continue browsing
Once you do so, open DAW and try to reactivate the plugin, it should work fine.
