I am a master candidate student with a student e-mail. After reading "NOTE: Activation is local and the software does not contact our server. Therefore activation keys cannot be deactivated. Please use the 30-day trial to test the software on the computer you intend to use long-term, before registering it here. This is particularly important for students because they can only register one computer.", I decide to use the 30-day trial before a student license. Now, I need to apply for a student license. After using my student e-mail dress and getting the green success recovery, I have waited for it for half a month without a new recovery e-mail. What should I do?
