The license code includes your first and last name and is case-sensitive. Copy and paste the WHOLE thing including your name, the asterisks, the number and the three letters at the end:

First**Last**1111111SUL

The code is stored in the After Effects preferences file so if you delete your prefs or you log in as a different user on the same machine you will need to re-enter the license code. If you’ve misplaced your license code, you can retrieve your license code here: http://license.aescripts.com/

Whenever there is an update, all you need to do is replace the script file and the license code will be automatically recognized.
