Do you get your subscription from Adobe or the school?
If it's paid by your school, contact your school's IT dept for assistance.
If your plan is active, payment & student elegibility details are current, you should be able to log-in to your Creative Cloud desktop app with your PAID ID and password.
1. Open CC Desktop App.

Hope that helps.
