If you use a Mac, you can first launch the trial version, click on "Help" on the menu bar, and then select the "Enter Keycode" or "Register XXX". In the registration window appears, you need to copy-n-paste the keycode received to the box and press "Register" to complete the process.
Note: since the license code is letter-sensitive, please COPY and PASTE the code. And don't add any blank before or after it.

If you see your app has been updated to a more advanced version, you can update your copy of that app to this newer version. Just delete the existing copy from your computer first, download a copy of this app’s newer version, install it on your computer, and then activate it with your personal keycode. Your keycode may not be valid on the app’s newer versions, in which case you need to contact us to get a new one.
There are several possible reasons for the failed registration. 1. This is caused by entry error. You'd better copy and paste the license code to avoid a typo.
