Mathcad student license

Dear PTC, I work as a part-time teacher on an on-call basis, and I am also an appointed assessor for the Danish Electrical Service Engineer education program. For this reason, I would like to request an extension of my Mathcad student license(prime 10.00 or 11.00 or newest version) for one additional year. I will, of course, be happy to pay any applicable fee for the extension. Proxi.id Support have successfully verified me. Could you please let me know if this is possible, and if so, how I should proceed? Thank you in advance for your assistance. Kind regards, Thomas Thomsen
