Changing single student license to new pc

Hello, I have used Rhino for university for some time and now that i’m changing to new pc I want to transfere the license from my old pc to the new one

I have followed the guidelines of trying to deactivate the old license and then use it on rhino the new pc, but when i click on the Change your license key button it only lets me login on my accout and tells me that the licence has been changed or asks me to insert a new license. I know that I probably missed something ovious but do you have any advice on this? Thank you very much
