A small problem

Good evening! There was such a problem.I'm a student. I have MathCAD Prime 8.0.0 installed. I used the trial version, and unfortunately it ended. It turns out that I need to purchase the paid version, right? And there is another problem, I'll be honest, to use this program, I created a new account every time. Now, when I receive a trial version, namely a license, a window pops up that I have received the maximum number of licenses for this program. What should I do?
