Not receiving the second mail for installation

I have requested the academic user signup some hours ago and I’m still waiting for receiving the second mail with the license. Is this normal? Can you help me, please?

Thanks

Hi Amaya,
We verified your license request earlier today. Please confirm you received the second email. You can send me an email at spunjani@structura.bio to let me know.
Thanks,
Saara

I received everything correctly.
Thank you for your help.
