Trial License Expired, unable to revert to Free license?

I installed the Katalon Studio trial license to evaluate and reported back to my Manager that this tool is worth pursuing for purchase (a process that may take some time).

However, my trial license has expired so I’d like to revert to the free license so I can continue working on some automation (and learning the tool). I deleted the old install folder and downloaded the free version but continue to get the activation dialog when launched.

Is there a way to revert from a Trial license to the free version?

Just got though the activation dialog.
You would notified that your trial has already been expired.
Just ignore it.
You can start Katalon Studio. — It will be using a Free license, with less capability than Enterprise version.
