Hi Raul,
Thanks for using our plugins and welcome to the forums!
Sorry you are having issues with this.
We are investigating why this still happens even if clearing transients. However, usually after a couple hours the options should be available.
Make sure that you have the license key saved under Events > Settings > Licenses tab.
In case you didn’t do it like this, then after entering the license key please wait for the green success message to appear and then click the Save button.
Clicking on Save before the success message usually results in the license key not being saved.
Let me know if you are still having issues with this and I’ll be glad to help you further.
Cheers,
Andras
