Hi
I'm another IT Administrator managing Intel Quartus software for our department needs, and i happened to see your post. I don't think the Intel Licensing people did not see your information posted, You may need to reply using a private message as indicated.
(I've been through this already as well.)
Once signed in, click on your user profile (little round avatar at the top of the webpage on the right side) and then click Messages in the drop down menu.
From there you can create a private message to the "AR_A_Intel" user account to provide your license details.
I hope you have already found a solution, but if not try this.
Cheers!
