If you’re certain that the code and email address are correct, please check you are using the latest version of the software and have selected the right license type in the activation window. In most cases, this will be a single user license (the default).
Note: Activation codes always start with ‘HUE’ or ‘INT’ while license keys are long sequences of letters and numbers. Our activation codes do not use the letter ‘o’, so any ‘o’s in your code should be entered as a zero (‘0’).
Please contact us if the problem persists, ensuring that you include your activation code and account details so that we can check for problems.
