Solution
- Start Diamonds.
- Go to Help > About Diamonds
- Click on the button ‘License info‘.
- Go to the tab page ‘Licenses to use in next session‘.
- Uncheck the licenses you don’t have.
- Restart Diamonds. The message should be gone.
Keep in mind that when you do purchase the unselected modules someday, you check the boxes again. Otherwise Diamonds will not search for those modules.
