Activate your license to remove size-limits

Hello, I would like to ask if the size-limits of ampl is permanently removed after activation, or only 30 days, and how can the restriction be lifted after 30 days

For AMPL the limits are lifted as long as the license keeps getting renewed (this will keep happening as long as terms and conditions are respected). For commercial solvers, the limits are lifted during trials but it is possible to apply for trial extensions.

Thank you. As a student, I just need no limit on the number of constraints
