Hi @GabeLogan,
Could you double check that the activation code is meant for your FreeMASTER Lite version.
Latest version of FreeMASTER Lite is 1.3.
During the installation process you should be prompted to visit NXP site (the link is also available in the product description in the component selection of the installation process).


You need to access that link only once when installing a newer version of FreeMASTER Lite.
After this is done, you will see your license entitlement next to other product versions:

Hope it help,
Iulian
