Katalon Studio Licensing

Hi Team,

I was able to use Katalon last week by 03/27. After that, when I opened the app, it just hung there with the “Activating” message. Today, I downloaded the latest version, I was able to open the app the first time after installing it, open my project and run some test cases. Then when I closed it, I said “Yes” for store whatever it said on the message. Then I opened the app again and the “Activating” message showed up and I am unable to use Katalon anymore.
Please help what I can do. Thanks,
