Activate Katalon License


This is a companion discussion topic for the original entry at https://docs.katalon.com/katalon-studio/docs/activate-license.html

When I invoke the Katalon Enterprise trial version, the activation window popped up. I entered the email, and the correct password, but the Activate button is still in disabled state.
Does it mean, it is already activated ?
For the fact, the activation code is visible below the password field.
