Hi John,
Please try the following:
- Check the Deactivate license key checkbox in the license screen and save
- Uncheck it and save
- If that still does not work, then please deactivate/reactivate the plugin and try activating the license key again
Sorry for the hassle. The 3rd party API key manager I use can get annoying sometimes, but I have yet to find a better alternative.
Cheers,
Vinny
