Student liscence on PTC MathCad 8.0
When I enter my new liscence key, it always tell me to try later. So I looked at the email and since i'm on the student version, it tells me that I need to send my student id and a proof of scholarity but there is no email mentioned for me to send it. Where do i send it? And is that why I can't activate my liscence key?
