I Cant Re activate my unity license!!!

Hello i have recently been using unity to create a game, when i hit a downfall in my game i needed a 3d modal. i asked my friend to make one for me, he has took a long time in doing so which lead to me trying to open unity to find that i cant because it has expired. Now you may be thinking well click the re-activate button, i can’t because i don’t have internet on that computer so what do I do now!

Find a way to get internet on that computer, even if only temporarily. You need to connect to the internet to activate your license because it allows Unity to ensure the license is valid. There are a huge variety of ways to connect a computer to the internet, including routing it through another computer.
