Hi @CarlosRodriguez_DRP ,
I take it you are on the latest version of Drone2Map? (2023.2.1)
Please also check that you are on one of the foundational user types required, Creator or Professional.
Lastly, I would make sure that your license is still current and hasn't expired since you said you haven't used it in quite awhile. Its possible that you are still able to assign it in AGOL with it being expired.
If all of that seems correct, then I would reach out to technical support where they can troubleshoot further.
Regards,
Mark
