Hi @naomi_nomura,
The number of licenses was increased on your account - it was limited by a system mistake, by default, we allow a much larger number of registered devices.
Please note that although we allow multiple FreeMASTER Lite licenses per user, and are expected to be used by the original requester. Any NXP registered user can obtain FreeMASTER Lite license free of charge.
Kind regards,
Iulian
