If you have already activated the plugin and still see the watermark on the footage please try applying it to a clip and changing any settings in the plugin slightly (e.g. changing the Threshold from 20 to 19). Host apps cache everything and this will force it to re-render, which makes the watermark go away.
You can also try clearing the cache manually by:
Premiere – https://helpx.adobe.com/premiere-pro/kb/clear-cache.html
After Effects – Choose Edit > Preferences > Media & Disk Cache (Windows) or After Effects > Preferences > Media & Disk Cache (Mac OS), and select the Empty Disk Cache button.
Final Cut Pro – Select one or more projects in the Final Cut Pro browser. Choose File > Delete Generated Project Files. Select Delete Render Files and click OK.
If clearing the cache does not work, then check this location:
C:\Users\Public\Documents\Digital Anarchy\Receipts (Windows)/Users/Shared/Digital Anarchy (Mac).
There should be a “.receipts” file there.
If that file’s there, the plug-in is registered on this computer. In the host app, try clicking on a different frame in the sequence — the preview doesn’t always update after registering. If this license is in use on any other machines, that may be causing a license conflict that causes the watermark to appear.
If the watermark is still there, try deleting the effect from your clip and closing the host app, then deleting the “.receipts” file. Re-open the host app, make sure the watermark is gone now that Flicker Free is not applied, then apply Flicker Free and register it. If the license file was moved or edited at any point, it may need to be re-created by re-registering the plug-in.
For older versions of the plugins (Flicker Free 1.0, Beauty Box 4.0, etc) there should be a file called Licenses.txt in C:\Users\Public\Documents\Digital Anarchy. Delete this file instead.
