This does work after messing around.
you need to log in with a burner gmail email.
this gives you 10 credits then you will get a email
with a password use the nero start app as this is where
you enter your activation code.click the sign up for newsletter
this gives you another 20 credits once you on the middle left side
there a option to select enter activation code paste this in
and then it will make your account Pro activated for the whole year
with the full 530 credits for AI Server GPU which is supposed to be
x100 faster then what GPU i dont know lol.
tired to sign up in app and was getting grey bars so used my burner gmail.
as this allow automatic sign on.
