Can't use Mathcad on my laptop

Hello, I own a student license and I use a desktop to make my school work at home but i do own a laptop that I take to classes due to it's portability, even being worse than my home desktop, I would love to use Mathcad on both but when I try to activate my license on my laptop it says that the maximum number of license requests were made, if I can't use the software on both my desktop and laptop it gets slightly useless, so I would love to solve this issue
