Help with signing in

I'm so frustrated at this point. Whenever I try to sign in using my school account, the school district pays for, it says "more information required." You're allowed to have 2 devices per adobe account. So the first device I have is my school iPad, I would like to have my illustrator app on my desktop as well. I don't have any devices activated, other than my school iPad and it still won't let me sign in. I feel like I've tried everything. To the right is the dreaded screen. And no- learn more does nothing.
