Activate license

[IK_10610461]

Good afternoon
I`ve received License file on my email but I don`t understand how to apply it. When I use .dat file for activate nothing happens. I still see "29 days left".
How fix it?

Yes, it really works, but I still have a notification "25 days left". Does MathCAD actually plaid for students? What will happen after 25 days? It really will stop working?
