Hi @Mateoo_47
We see that you have not generated a license key in Altair one, or do not have one with your latest account, Your account is verified for student edition use and you can now use the free student edition,
You now need to follow the steps here in this community post below - exactly in order to generate the license key , Start from step 2 since your account is already verified then follow all the steps there to activate the software.
